Caterpillar’s industrial motors are found in sizes from 15 kW - 4,900 kW
A total of 2,500 OEM (Original Equipment Manufacturers) throughout the world incorporate various CAT motors in their series of manufactured equipment. An especially important advantage with CAT industrial motors is that they are environmentally certified and their exhaust emissions are well below the permitted limits. Caterpillar has long been a driving force in the development of industrial motor technology, and the steadily improved components in the motors have reduced exhaust emissions, at the same time as the power of the motors has increased. An important change in this development was the introduction of electronics into the motor.
ACERT
In order to meet the ever more stringent requirements to exhaust emissions and more environmentally sound motors, Caterpillar has developed its own system to meet them.
ACERT (Advanced Combustion Emission Reduction Technology) combines several patents to form a complete technology. ACERT was first developed to use in engines for the "on-road" market, and was later transferred to industrial motors and is also on the way to becoming a marine standard.
ACERT currently satisfies TIER 3 (U.S) / stage IIIa (Europe).
ACERT consists of these main groups:
-ADEM 4 electronics
-Serial turbocharging
-Variable valve control
-Sequentially controlled injection
-Exhaust filtration (catalytic converter)

EMC (Electronic Control Module)This is the main unit for controlling all electronic communication in the electronic motors. Since 1987, Caterpillar has used electronics to control injection and regulation of its motors. Today, virtually all motors, with a few exceptions, are electronically controlled. This provides a number of advantages for end users, and not least our customers, who integrate control systems and monitoring into the manufactured product.
All of the motors offer the J1939 data link, which provides a continuous stream of all parameters, as well as the opportunity for accurate and efficient control of the motor.
The advantages of electronic motors are as follows:-Significantly lower emissions of NoX, CO and environmentally harmful exhaust gases.
-Lower fuel consumption, especially at low load.
-The motor "protects" and monitors itself to avoid failure.
-The opportunity to extract signals via data-link, which reduces installation costs significantly.
-More even and stable operations, with less visible smoke and cold start difficulty.
-The opportunity for metering diesel consumption exactly, as well as the motor load.
