Complete Caterpillar C15 ACERT T4 engine

The Caterpillar C15 ACERT T4 engine is a six-cylinder inline (I-6), four-stroke diesel unit designed for heavy industrial or mobile applications that require compliance with strict emission standards. The displacement is approximately 15.2 liters (~928 in³), with a bore of approximately 137 mm and a stroke of approximately 171 mm. The ACERT system allows for optimized combustion and reduced NOx and particulate emissions, meeting EPA Tier 4 Final and EU Stage IV emissions regulations. Turbocharging is accomplished through a turbocharger combined with an aftercooler to maximize torque at low RPM and performance under heavy load. The injection and control system is electronic, managed by an ECU unit, with advanced monitoring and adjustments tailored to working conditions. The engine block, crankshaft, connecting rods, and lubrication system are designed for high durability and more efficient maintenance.
