Durability & low noise Designed for the easiest, fastest and most economical installation. Well bal-anced to produce smooth and vibra-tion-free operation with low noise level, featured with high torque. To maintain a controlled working temperature in cylinders and combustion chambers, the engine is equipped with piston cooling. The engine is also fitted with replaceable cylinder liners and valve seats/guides to ensure maximum durabil-ity and service life of the engine. Operational economy and Low exhaust emission The state of the art, high-tech injection and air charging system with low internal losses contributes to excellent combusͭtion and low fuel consumption. The TAD1250VE complies with EPA/ CARB Tier 3 and EU stage III exhaust emission regulations.These regulations are met by using V-ACT (Volvo Advanced Combustion technology). V-ACT includes a flexible high pressure fuel injection system, an air management system including an internal exhaust gas recirculation device and an enhanced electronic controller. Easy service & maintenance Easily accessible service and mainte٭nance points contribute to the ease of service of the engine.
