Product Description

The Volvo D7D is an inline six-cylinder diesel engine with a displacement of 7.15 liters. This engine is designed to be used in heavy-duty applications, such as long-haul trucks and construction equipment. Some of the key features of the D7D engine include:

  • High pressure fuel injection system: The D7D engine uses a common rail fuel injection system that delivers fuel at high pressure to improve combustion efficiency and reduce emissions.

  • Exhaust gas recirculation (EGR): The D7D engine uses an EGR system to reduce NOx emissions by recirculating a portion of the exhaust gas back into the engine.

  • Variable geometry turbocharger: The D7D engine is equipped with a variable geometry turbocharger that adjusts the turbine geometry to optimize boost pressure at different engine speeds and loads.

  • Electronic engine management system: The D7D engine is controlled by an advanced electronic engine management system that monitors engine performance and adjusts fuel injection, turbocharger boost, and other parameters to optimize fuel efficiency and reduce emissions.
