Engine
ACERT ® Technology optimizes engine performance
Cat ® C15 Engine
The Cat C15 engine with mechanically actuated electronic fuel injection (MEUI) powers the 374D L.
The C15 has ACERT
® Technology, a series of Caterpillar engineered innovations which provide advanced
electronic control, precision fuel delivery and refined air management compliance.
Increased Power
The maximum power is 355 kW (476 hp), 18 percent more power than the 365C. The Power Management
System (PMS) is also available to manage productivity and fuel economy.
Improved Fuel Efficiency
The 374D L fuel maps provide additional power and performance with optimized fuel consumption
through flexible power settings incorporated into ADEM™ controller.
Improved Reliability
The titanium-aluminum alloy rotor in the turbocharger improves reliability/durability and contributes
to faster response of the turbocharger.
Hydraulic Cooling Fan
The 374D L uses a variable speed, hydraulically-driven fan for quieter operation and reduced fuel
consumption during cooler ambient conditions.
Reversible Fan
A reversible fan option is offered as an attachment. The reverse function is operated through the
monitor. By selecting this function, the fan rotates in the opposite direction for a preset time to help
clean the cooling package for increased uptime and reduced service cost.
