Engine Caterpillar C18

Industrial CAT C18 engine manufactured by Caterpillar (USA) – 6-cylinder, in-line, 4-stroke, direct fuel injection, turbocharged with air-to-air aftercooling system, electronic control unit (ADEM ™ A4), MEUI fuel system.

Engine power Caterpillar C18 – 700-1130 HP at a crankshaft rotation speed of 1500 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.

Power characteristics depend on engine modification:

• Caterpillar C18 ATAAC — 535 kW or 727 hp;
• Caterpillar C18 — 597 kW or 812 hp;
• Caterpillar C18 ATAAC2 — 775 kW or 1054 hp;
• Caterpillar C18 ATAAC3 — 831 kW or 1130 hp

Advantages of the Caterpillar C18 ACERT diesel engine

• Narrow rings fitted to the Monotherm piston and tighter manufacturing tolerances ensure superior assembly performance.
• Lower fuel consumption results in lower operating costs and lower emissions.
• The MEUI fuel system is highly reliable due to its special design.
• Redesigned cranks are stronger and more secure.

Caterpillar® C-18 automotive engines are designed for normal operation on road vehicles up to 65 tonnes. To obtain a balanced vehicle performance and fuel consumption for the C-18 engine, select axle and tire specifications such that the following condition is met:

• 1450 – 1550 min-1 at a speed of 90 km / h.

When at least one of the following conditions is present, extra care should be taken when selecting the proper transmission and axle characteristics:

1. Poor road surface;
2. Elevation angles – 8% or more;
3. Gross vehicle weight exceeds 65 tons.
