Volvo D7E Engine — Reliable 7.2L Diesel Power for Trucks & Excavators

Volvo D7E Engine — Product Features

The Volvo D7E is a 7.2L inline-six diesel engine widely used in medium- and heavy-duty trucks, buses, construction machinery, and industrial equipment. It combines powerful power output with excellent fuel efficiency and environmental performance, making it a classic Volvo powertrain.

🔧 Product Features
1️⃣ Powerful Power Output

With a displacement of 7.14 L and an inline-six-cylinder design, it delivers ample power.

Power ranges from 240–290 HP (177–235 kW) to suit various operating conditions.

Maximum torque ranges from 920–1200 Nm, delivering strong pulling power at low rpm, making it suitable for heavy-duty operations and long-distance hauling.

A turbocharged and intercooled system ensures stable high power output.

2️⃣ Fuel Efficiency and Economy

A high-pressure common rail fuel injection system precisely controls fuel injection and improves combustion efficiency.

Optimized combustion chamber design reduces energy waste and significantly lowers fuel consumption.

High torque at low speed reduces frequent gear shifting and improves operating efficiency.

3️⃣ Environmental Protection and Emission Control

Complies with Euro IV/Euro V emission standards, and some versions support EGR (Exhaust Gas Recirculation) and SCR (Selective Catalytic Reduction) systems.

Reduced nitrogen oxides (NOx) and particulate matter (PM) emissions, contributing to environmental friendliness.

Lower operating noise meets environmental and noise requirements for urban and road construction projects.

4️⃣ Durability and Reliability

The cast iron cylinder block and high-strength crankshaft provide a robust structure and excellent fatigue resistance.

Optimized lubrication and cooling systems ensure stability under long-term, heavy-load operation.

Long design life and extended maintenance intervals reduce operating costs.

5️⃣ Versatile Applications

Trucks/Tractors: Meet the efficient power needs of medium- and long-distance freight and logistics transportation.

Buses/Transit Vehicles: Provides smooth, quiet, and fuel-efficient power for models like the Volvo B7R.

Construction Machinery: Commonly used in excavators and loaders, providing powerful construction power.

Industrial and Power Equipment: Can be used as a stationary power unit for generator sets or industrial machinery.
