Caterpillar engine with ACERT Technology

Caterpillar® heavy equipment rolled out of the assembly line with the latest engine technology. The model was first transmitted is D8T. Several other models followed including D9T, 365, 385, and four Articulated Trucks. At the end of April, a total of 26 models of heavy equipment was available! Each machine uses a Caterpillar engine with ACERT ™ Technology, the results of research and development of more than $ 500 million and more than 250 patents. This engine meets EPA Tier 3 emissions regulations governing the United States of heavy equipment of non-highway, which force on January 1, 2005 for engines with power from 300 to 750 horsepower.

ACERT Technology is another example of why Caterpillar continues to be a leader in North America in search highway. Truck engines with ACERT recorded more than 70 million miles every day. In fact, the Caterpillar plant sent more than 16,000 engines per month. Record the highway, combined with decades of experience Caterpillar in non-highway business has meaning customers will continue to receive the performance of the engine and the best engine production.

Engine emission regulations for heavy equipment is not new. The first regulation enacted in 1996, and the Tier 2 regulations followed in 2001. The standard is met by adapting existing technology, but the aggressive Tier 3 requirements require a breakthrough. Caterpillar introduced ACERT Technology to meet EPA '04 regulations for on-highway truck. Earlier, Caterpillar heavy equipment engines with ACERT start field testing throughout the United States, Canada, and Europe. 

Now there are more than 350 such tools in the field. In total, all of them have worked more than 520,000 hours. Heavy equipment is working on a variety of applications typical for Cat equipment-from construction, mining, until the waste. And heavy equipment working in various types of conditions. One track-type tractor has been successfully working on road construction projects at an altitude of 8100 feet. ACERT Technology reflects a series of revolutionary improvements and gradually developed by Caterpillar. For example:

Fuel system allows multiple injections in each combustion cycle. Little fuel is injected at the right time to achieve a combined fuel economy and lower emissions. Advanced air systems generate cooler air in the combustion chamber. Wastegate turbocharger provides a low-end response is excellent. In addition, cross-flow cylinder head provides direct air path to the engine.

Caterpillar engineers worked with approximately 125 variables to find the optimal balance. There are more than 10 million combinations possible combustion. The engineer is challenged by the interrelated relationship between (1) the reduction of emissions, (2) the performance of the engine, (3) fuel efficiency, and (4) engine durability. Everything is not just complementary goals. Increase emissions, for example, can have negative effects on fuel efficiency. The end goal is no different than its intended purpose since Caterpillar established-to give customers the cost of owning and operating the lowest, and the lowest cost per unit of material moved.
