TAD952VE

242 kW (330 hp) crankshaft power acc. to ISO 3046

The TAD952VE is a powerful, reliable and economical Industrial Diesel Engine built on the dependable Volvo in-line six design.

Durability & low noise

Designed for the easiest, fastest and most economical Installation. Well-bal-anced to produce smooth and vibration-free operation with low noise level, featured with high torque.

To maintain a controlled working tem-perature 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 combus-tion and low fuel consumption. The TAD952VE complies with EPA/CARB Tier 3 and EU stage III exhaust emission regulations.

Easy service & maintenance

Easily accessible service and mainte-nance points contribute to the ease of service of the engine. These regulations are met by using V-ACT™ (Volvo Ad-vanced 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.
