| Engine | A combination of innovations working at the point of combustion, ACERT Technology
optimizes engine performance while meeting EPA Tier 3 emission regulations.
|
|
| Product Link | The 365C L is "Product Link Ready" from the factory. |
|
| Diesel Engine | The Caterpillar C15 with ACERT Technology, is a 15.2 liter, six-cylinder, 302 kW (404 hp) engine with mechanically actuated electronic fuel injection (MEUI) and overhead camshaft. ACERT Technology provides outstanding engine performance through advanced electronic control, precision fuel delivery, and refined air management. | 
|
| Fuel Consumption | The ADEM™ A4 controller uses sensors throughout the engine to manage engine load and performance. The ADEM A4 controller is the muscle behind engine responsiveness, self-diagnostics, controlling emissions, and fuel economy. |
|
| Fuel System | The C15 uses a mechanically actuated electrically controlled unit injection (MEUI) system. The MEUI system combines high- pressure injection and electronic control in a single compact unit. The electronic unit injector is an integral part of the C15 fuel system. Computerized electronic control provides precise metering and timing of fuel injection. |
|
| Cooling System | High capacity, side-by-side cooling system allows operation in ambient temperatures up to 52 degree C (126 degree F). The Electric Power Control (EPC) controls the fan speed based on coolant temperature and hydraulic oil temperature for optimized cooling. |
|
| Turbocharger | The C15 uses a water-cooled, center-section waste gated turbocharger for improved performance. This turbocharger controls the air volume to the cylinders and works efficiently during low and high load conditions. |
|
| Emissions | ACERT Technology is a differentiated technology that reduces emissions at the point of combustion. The technology capitalizes on proven Caterpillar leadership in three core engine systems: fuel, air and electronics. |
|
| Cold Weather Starting Kit | The kit consists of two additional batteries, heavy-duty harness, large capacity starting motor, and the ether starting aid. With this kit, the 365C has the capability to start at -32 degree C (-25.6 degree F). |
