The Caterpillar 324D is a 24-ton excavator equipped with a CAT C7 ACert engine and rated at 140 kWh.The CAT C7 engine using ACERT technology delivers higher engine power and operates at lower RPM, resulting in improved fuel efficiency and reduced wear.
ECU: The ADEMTM A4 (advanced diesel engine management) electronic control module manages fuel delivery for optimal fuel consumption efficiency. The controller uses sensors in the fuel, intake, exhaust, and cooling systems to provide flexible fuel mapping and allow the engine to respond quickly to changing operational requirements. It can track the condition of the engine and the machine while keeping the engine running at maximum efficiency.
Cooling system: To reduce fan noise, the cooling fan is driven by the equipment ECM through an electrically controlled viscous clutch. The optimal fan speed is calculated according to the target engine speed, coolant temperature, hydraulic oil temperature, and actual fan speed. The new structural layout of the CAT C7 engine separates the cooling system from the engine compartment.
