Mack truck engines are the result of research, experimentation, hard work, and decades of evolution. The engines are high-quality and meet top performance standards.

History of Mack Truck Engines

For over a hundred years, Mack Truck engines have ruled America's truck engine manufacturing market. In 1890, Jack Mack accepted a carriage building job in Brooklyn, New York. It was a company of Fallesen and Berry. Soon, Gus, the younger brother of Jack, joined him and eventually purchased the company. After one year of getting into the truck manufacturing business, their third brother, William, also joined in.

With three brothers working together at the helm, they transitioned from building carriages to wagon construction. Along with wagon construction, they also shifted their focus on new steam and electrically powered motors. The three brothers got their first break with Prospect Park, a tourism company in Brooklyn. The tourism company contacted Mack and placed an order to design, build, and manufacture a tourism company vehicle entirely by Mack. This meant the engines and everything else; Mack built the sightseeing bus. And this is the first bus that bears the name "Mack."

The tourism company was pleased with the bus and thus ordered a second. The second bus was ordered in 1901. Mack Truck became an established company, and since then, the company has never looked back. By 1902, the Mack Brothers company was established. Right from the company's inception, Mack started building Mack engines. They focused on heavy-duty engines, which could be run both off-highway and on-highway.

Mack truck engines have always been known for their power and foot-pound torque output. They measure power to the ground rather than high horsepower. A primary feature of Mack that distinguish the company from the competition is the transmission. Mack engines are made for a long lifespan and durability. You will see Mac truck engines being used in public bus fleets, dump trucks, fire engines, and garbage trucks. When it comes to most of the Mack truck engine’s running rate, it is primarily 1400 to 1800 rpm, however, these engines aren't made for high running rates. The company has designed different types of Mack truck engines for various industries, such as compressors, mining, gas, oil, agriculture, pumps, constructions, and power generation.

By the year 1905, the company opened another production facility in Allentown, Pennsylvania. By then, they already successfully built over 51 vehicles with engines.

Mack Truck Engine Technology

Since its inception, Mack Trucks have demonstrated that the company is committed to industry technology advancement. Mack has been consistent in quality with its design, powertrain components, and engineering. Mack Maxidyne's engine, built in 1967, became a revolution in the conventional truck engines market. Many of such innovations were already happening in Mack. New technologies are being implemented so that they can meet the requirements of their customers.

Soon, GHG 2017 MP8 engine with new transmissions and turbo compounding was manufactured and added to Mack's portfolio.

Apart from these, Mack mDRIVE™ HD 13- and 14-speed and Mack MP® 8 engines with turbo compounding were manufactured as well in 20187. Both the engines have two low-ratio creeper gears. These engines provided trucks with enhanced stability while maintaining their efficiency. Mack mDRIVE HD 13 provides a low reduction gear ratio, whereas Mack mDRIVE HD 14 comes with a second ultra-low-speed reduction gear, which is ideal for heavy-haul maneuvering, and low speed.

Most of the latest model Mack truck engines have a water-cooled feature. With powerplants ranging from 11 to 16 liters, you can expect Mack truck engines to deliver the performance and power needed to get a job done.

The 2017 Mack MP Series motors get critical enhancements eco-friendliness, power, and efficiency while diminishing ozone-depleting substance discharges. On account of a few overhauls and improvements, the new motor

s help eco-friendliness from 2.1 to 8.8 percent contrasted and earlier model year motors.

Mack's 11-liter MP7 and 13-liter MP8 motors highlight a refreshed wave cylinder plan that raises the pressure proportion and empowers the fuel's complete ignition. At the same time, a typical rail framework all the more accurately infuses fuel. Joined with a two-speed coolant siphon, these highlights help increment MP7 eco-friendliness by up to 5.1 percent and MP8 eco-friendliness by up to 5 percent.

Some extra upgrades were made to the two motors, including another two-piece valve cover, shimless rockers, and a low-pressure fuel framework with an improved, coordinated after-treatment dosing module to diminish upkeep needs. A refreshed, twofold walled EGR stream sensor decreases buildup and ash development in chilly climate, while another admission choke empowers a quicker warm-up when the motor is turned over.

With another 425-drive rating, the 2017 MP7 offers a 13-liter force in a lightweight, productive 11-liter bundle ideal for delicate weight applications.

The refreshed 2017 Mack MP arrangement motors supplement Mack's as of late dispatched Mack mDRIVE HD 13-and 14-speed mechanized manual transmissions. With up to two low-proportion creeper outfits, the new mDRIVE HD variations give improved stability to weighty loads while keeping up legitimate intending for eco-friendliness at speed.

Fuel Injection

The delivery tube, which is known as rail, is required to keep the continuous high pressure. The pressure will be around 23,000 pounds per square inch. In some cases, the pressure can increase. Into the combustion chambers cylinders, fuel will get sprayed finely. This process is done through the nozzles. ECU determines the pressure, how long it should last, and other factors.

After all the steps are completed, the fuel will find its way where it needs to go. The air will be heated as well to a higher temperature. The fuel sprayed of the fuel, which has more temperature than the auto-ignition, will make the fuel react almost instantly with the oxygen. You can expect air temperature up to 526 °C or 979 °F. You will find diesel engines working on either two-stroke cycles or four-stroke cycles. Let's try to understand them.

Two-Stroke Engines

When we say two-stroke engines, it will include a process where the piston will only move up and down per ignition. Following are the main components of two-stroke engines.

Exhaust and Intake- When the air gets blown inside the cylinder, it will push the old exhaust out via the valves. After that, both the inlet and exhaust valves will be closed. The piston will start moving upwards, which will compress the air, thereby heating it up. Once the piston reaches the cylinder's top, fuel will get injected, which will be immediately ignited.

Power- When the fuel mixture and air will start to burn, the piston will be pushed down. This will drive the crankshaft, whose work is to provide powers to the wheels.

Four-Stroke Engines

In the case of a four-stroke engine, there will be four stages or strokes, and the cycle will be repeated. In this process, the piston will be moved upwards and downwards twice per ignition.

Intake - Through the opening in the valves, air will be drawn inside the cylinder, and the piston will start to move downwards.

Compression- After that, the inlet valves will shut down, and then the piston will start moving upwards. This whole process will compress the air mixture and will begin to heat it up. Via the central fuel injection valve, the fuel will be injected into the hot gas and then ignite. Unlike gas engines, diesel engines don't require any sparkling plug.

Power- When the fuel mixture and air will start to burn and ignite, it will eventually push down the piston. This will drive the crankshaft to send power to the wheels.

Exhaust- All the steps mentioned above will open one of the outlet valve ends, which will let out the exhaust gases and return the piston.

What Makes Diesel Engines Better?

If you compare diesel engines with gasoline engines, you will notice that they are more efficient than gasoline engines. You will get better performance with the same amount of fuel used. Diesel engines use up to 30% less amount of fuel.

Another reason why diesel engines are better is that they emit a lower amount of CO2, which is up to 20%. Diesel engines are always better and more powerful than gas engines. Diesel engines will provide you with a longer lifespan, which means that they are durable.
