Engine Caterpillar C9

CAT C9 ACERT industrial engine manufactured by Caterpillar (USA) – 6-cylinder, in-line, 4-stroke, direct injection, turbocharged with air-to-air aftercooling, electronic control unit (ADEM ™ A4), HEUI ™ fuel system, high efficiency of oil filters, lighter design of the cylinder block, split connecting rods.

Engine power Caterpillar C9 – 278-381 HP at a crankshaft rotation speed of 1800-2200 rpm. The engine meets Tier 3 (US EPA) and Stage IIIA (European Union requirements) emission standards using Advanced Combustion Emissions Reduction Technology (ACERT). It covers 4 systems to reduce the toxicity of exhaust gases and covers:

• fuel system;
• fuel combustion process;
• clean air intake system;
• implementation of an electronic control and management system.

Specifications

IND – A mode (continuous operation) – the mode of continuous operation of the engine in severe conditions, when the engine is operated at maximum power and maximum speed up to 100% of the working time, without interruption or periodic load reduction.
IND – B mode – engine operation mode, in which the power and (or) rotation speed periodically decrease in comparison with the maximum value (the duration of operation at full load does not exceed 80% of the total operating time).
IND – C mode (intermittent mode) – operation of the engine with a periodic increase in power and (or) speed to maximum values ​​(duration of operation at full load does not exceed 50% of the total operating time).
IND – D mode – engine operation mode, in which periodic increase in power to the maximum value is allowed (duration of operation at full load does not exceed 10% of the total operation time).
IND – E mode is a mode in which maximum power is required for a short period of time for starting or in the event of a sudden overload. For emergency operation where the normal power level is not sufficient (run time at full load does not exceed 5% of the total run time).

Engine Operation:

The power of this engine is achieved due to the volume, and not by strong forcing, which as a result significantly reduces the load on the engine parts and has a positive effect on fuel consumption. The redesigned fuel system has improved fuel economy by 4% over the previous version. The use of a variable speed supercharger allows for maximum torque from 1800 rpm. Compression brake extends pad life with 381 hp engine braking power. High quality workmanship improves the reliability of the engine.
