Premium high performance power.

Maintaining their outstanding reputation for high performance power even in the harshest conditions, the latest KTA range is jacket water aftercooled design. Its inbuilt step timing control system ensures optimum engine timing at all combinations of load and ambient temperature, improving cold starting and reducing light load fuel consumption to greatly enhance engine efficiency.

Aftercooler Large capacity integral aftercoolers are supplied with cooling water separate from the engine jacket. This provides cooler, denser intake air for more complete combustion and reduced engine stresses for longer life and low exhaust emissions.

Cooling System A two pump, two loop system must be employed; i.e. the engine jacket is cooled by one radiator or heat exchanger and the aftercoolers are cooled by a separate radiator or heat exchanger. Both cooling systems are independent of each other. The jacket water pump is supplied engine mounted from the rear of the gear cover. The aftercooler water pump is customer selectable and can be provided mounted on the front of the gear cover. Cummins provides conventional water inlet and outlet connections for the jacket system. Aftercooler water pump inlet and aftercooler core outlet connections are provided for customer use and ease of plumbing on the aftercooler system.

Lubrication Large capacity integral gear driven pump provides pressure lubrication to all bearings and provides supply for piston cooling. Cummins supplied large capacity oil pans are recommended for Prime and Continuous Power applications.

Pistons Pistons are dual Ni-resist, aluminum alloy, ground and shaped to compensate for thermal expansion which assures a precise fit at all normal operating temperatures. Oil cooled for rapid heat dissipation. Two compression rings and one oil ring. Utilizes offset piston pin for reduced susceptibility to liner cavitation.

To protect public health and conserve our planet's natural resources, legislation from the U.S. Environmental Protection Agency (EPA) and regulatory agencies in the European Union (EU) has, for the past decade, required that pollutants produced by diesel engines - such as nitrogen oxides (NOx), hydrocarbons (HC) and particulate matter (PM) - be reduced.

Throughout this time, Cummins Inc. has been at the forefront of the move to meet these new standards, becoming:

  • the first manufacturer to introduce EPA Tier-2 and Tier-3 products to the market - ahead of the regulatory deadline;
  • the first manufacturer to introduce EU Stage IIIA compliant generator-drive diesel engines to Europe;
  • the leader in innovative emissions solutions that focus predominantly on in-cylinder design improvements to eliminate most of the NOx, HC and PM before they are formed.

As a result, our diesel engines are not only very clean, but also retain all of their performance advantages without exhaust after treatment strategies that add cost and complicate maintenance for end users.

G-Drive Engines

  • Mid-range (1.3 - 9L) medium-horsepower engines (16 to 476 hp), providing the broadest Tier 3 range which further reduce Tier 2 NOx levels by 38%
  • Heavy duty (11 - 15L) 415 to 755 hp engines powering commercial operations
  • High-horsepower (19 - 78L) 675 to 3700 hp at both 1500 and 1800 rpm, designed to meet Tier 2/Stage II emissions requirements for electronics and diagnostics, base engine and turbocharging, power cylinder and fuel systems
