International company, which is a subsidiary of Navistar International, was formally known as International Harvester Company. This company is based in the United States, and Navistar International was founded in 1902. International's main objective is to build and manufacture high-quality trucks, but besides that, they also source their engines from Cummins, International. They make outstanding in-house engines for heavy-duty trucks for a fantastic performance. Their engines are typically suitable for medium-duty commercial vehicles.
International truck engines are a subsidiary of Navistar International. Navistar International runs its own International brands of diesel engines and heavy-duty trucks. Along with these, the company is known worldwide for manufacturing military vehicles. They run this operation through the Navistar Defence subsidiary. Navistar International has its headquarter in Lisle, Illinois, and has over 13,000 employees. The company deals through a wide range of outlets numbering close to 1000 scattered all over the USA, Brazil, and Mexico. The company also operates through 60 dealers who are based in 90 countries across the globe.
With the merging of Deering Harvester Company and McCormick Harvesting Machine Company in 1902, International Harvester Company was formed. They choose their center of operation as Chicago, Illinois. International Harvester Auto Wagon was born in 1908, which is the forerunner of the pickup truck. Throughout the years of operation, the company became one of the best manufacturers of truck engines and trucks and started diversifying its production. They started producing vehicles for construction and agriculture industries, ranging from different types of buses and commercial trucks. Cub Cadet and Farmall are the other two companies who are associated with Navistar International.
During times of poor agriculture economy, the company went through challenging periods. However, they came out of the problems, and in 1983, Navistar International started their Engine Division under the name International company and produced 6.9L IDI V8 diesel engines. These engines were developed for Ford vans and full-size pickup trucks. In 1985, Tenneco acquired the Agriculture division, and only the Truck and Engine division was left behind with International Harvester. The company's logo was designed keeping in mind their Agriculture division, but after Tenneco took over their Agricultural Division, the International Harvester redesigned their company logo and reintroduced themselves as Navistar International on February 20, 1986. The brand "International" is used for its wide range of product lines, run under the International Truck and Engine Corporation.
With the popularity of diesel engines, Navistar started becoming immensely popular during the 1980s and 1990s. They soon became the leading manufacturer of bus chassis, primarily school buses. The IDI diesel that the company manufactured got replaced by the T444E engine in 1994. On September 30, 2000, Navistar announced that they are moving their business from Chicago to west suburban Warrenville, Illinois. "NGV" trucks were introduced in 2001, which incorporated a brand-new design. In 2004, the company again entered the retail vehicle market; its series launched for the retail vehicle market was the International XT series. In September 2010, the company decided that they want to move to Lisle, Illinois, which is still their headquarter.
Currently, Navistar International is working on clean engine technology. It will be a Class 8 diesel engine that will be fully compliant with the U.S. Environmental Protection Agency standards. In July, the company stated that they would no longer be using the exhaust gas recirculation process. They are looking forward to work for SCR, which is a selective catalytic reduction process. Navistar International will also license Cummins Inc.'s urea-based after-treatment system. They will establish it to ICT+. The company is planning to incorporate to already existing MaxxForce engines and Cummins' after-treatment system so that they can meet the regulation of 2010 EPA emissions. The company president says that to implement a clean engine solution, the company is taking the route of cutting-edge technology to provide the most fuel-efficient and clean trucks and engines.
With the implementation of ICT+ technology, the company said that they are focusing on building EPA-compliant trucks and engines in every class of vehicles, which will use the combination of non-conformance penalties and earned emissions credits. As Navistar International has expanded its relationship with Cummins, the company is planning to offer Cummins ISX15 engine to a few trucks. All the new engines will incorporate world-class technology, which will provide rugged performance, long service life, availability, fuel economy, and reliability. The user will experience an exceptional driving experience; that's what is guaranteed by the company.
Take the A26 International truck engine for an example. It is suitable for heavier trucks and is good for haul large loads. It has a displacement of 12.4 liters, which makes the weight manageable. Because the weight has been reduced, vehicles will be able to haul more freight. If you compare this engine to its predecessors, you will notice that it is 5% more fuel-efficient, saves fleet or driver's fuel expenses, and 50 pounds lighter. The secret to all this is its variable geometry turbocharger. Of course, A26 is lightweight, but it can let you drive your truck uphill or downhill.
In terms of the International company engines, it will be accurate to say that they are a value for money deal. The company pays utmost attention to driver experience while building these engines. You will get best-in-class maintenance with the truck engines. International always tries to go one step ahead and think about the future while designing their engines in terms of technology. International takes their truck engine process seriously, and that's why their wide range of engines is unbeatable.
International company manufactures diesel engines, which means that their engines will work the same way other diesel engine works. Diesel engines are internal combustion engines, which means the air will be compressed in the chamber. After that, a high temperature will ignite the fuel, which will then get injected into the cylinder, thereby moving the piston. Here is the step-by-step view of how International truck engines work.
The first thing that one will have to do is turn the key in the ignition to begin the ignition process. Once you do that, the cylinders will start receiving an immense amount of heat. Heat is needed to kick start the engine. After that, fuel will get injected into the cylinders under tremendous pressure and eventually heat the cylinder. All of this will happen in just a few seconds. Drivers and haulers prefer diesel engines because it is less unstable, which is why they are easier to start. Manufacturers have also begun to install glow plugs, which pre-warms the air in the cylinder once the engine starts. With the augmentation of cutting-edge technology for fuel, the injection pressure creates a better and higher heart to touch off the fuel even without the requirement of glow plugs. However, even today, plugs are required for emission control. You will see these chambers in some of the vehicles even today, and that's there for better results.
After the ignition process is done, which is just a few minutes, you will move to the start light turn-on process. In this process, the fuel pump will be delivering the fuel to the engine from the fuel tank. The fuel before getting inside the fuel injector nozzles will first pass through a few fuel filters. This is done to avoid clogging the nozzles. Proper maintenance is vital.
The delivery tube, otherwise known as rail, will start to inject the pump at constant high pressure and start delivering the fuel to each of the cylinders. This process will incorporate a proper interval. In the form of a fine spray, the fuel will be supplied via the fuel injectors. The fine spray of fuel will get into the combustion chambers of the cylinders. This will be done via nozzles, which ECU, Engine Control Unit controls.
Along with this process, there will be a second process that will work simultaneously. This is required for the final power play. The fuel will be heated to an extreme temperature, which will help in injecting fuel so that it can ignite. Because of this high temperature and pressure, auto-ignition temperature will react instinctively. You can expect the air temperature to be over 526 °C. Diesel engines are also commonly referred to as compression-ignition engines. This is because the beginning of the combustion is mostly dependent on the air heated by the compression.
Now, diesel engines are available in two types. One is two-stroke engines, and the second one is four-stroke engines. Let's try to understand each of them briefly.
Exhaust and Intake- The air will be blown into the cylinder, which will eventually push the old exhaust from the valves. After that, exhaust valves and inlet will be closed. Next comes the piston, which will move upwards and compress the air to heat up. Once the piston reaches the cylinder's top, fuel will be injected, which will ignite it. Power- Once both the air and fuel mixture begin to burn, the piston will be pushed downwards, driving the crankshaft and giving the wheels the power to move.
Unlike two-stroke engines, the piston's movement process, which is its up and down movement, will happen twice.
Intake- First comes the intake, where the air will be drawn into the cylinder. It will go through the opening in the valves and make the piston move downwards.
Compression- Then comes in compression. The inlet valve will shut off, which will move the piston upwards. This process will compress the air and fuel mixture, which will eventually heat everything up. Into the hot gas, fuel will be injected via a central fuel injection value, which will make it ignited.
Power- Once both the air and fuel mixture begin to burn, the piston will be pushed downwards, driving the crankshaft and giving the wheels the power to move.
Exhaust- The outlet valve will open up in one of the ends, which will let out the exhaust gas. These are the working process of two-stroke and four-stroke engines. When it comes to the sizes, two-stroke engines will be smaller. Four-stroke are more efficient and produce better power during each rotation. But since they work more, they will need to be cooled down and will require lubrication.
Diesel engines are superior when it comes to their performance. They are energy efficient and require less fuel. The number of miles you will be able to travel with gasoline engines, the requirement will be lesser with diesel engines.
Diesel engines are designed to work and operate smoothly in high-temperature regions. Diesel engines supply more energy, which is why they become better for any road condition.
If you are thinking about buying International truck engines, you will be happy to know that there are many models available for the said brand. These are energy-efficient and made with cutting-edge technology. However, if you want to save money on your purchase, you can think of used International truck engines.
Used International truck engines are affordable and will come in good condition, provided you purchase them from a reliable dealer of International truck engines. Here are a few tips to consider before buying an engine from a used International truck engine dealer.
Just like first-hand engines, the used engine models must have gone through proper testing, such as load bank tests and other inspections. This should be done to check whether the engine is reliable or not. The seller or supplier will do these checks.
Finally, it is better to choose a dealer who provides you with a warranty on the engine you want to purchase. This way, you won't have to worry about repairs at least for one year or more, depending on the warranty.
