904D-E28T Industrial Diesel Engine

< Back


The Perkins® Syncro engines offer a compact power solution for off-highway applications in construction, agriculture and industrial.

For our customers these compact, 4 cylinder engines provide excellent performance in power, peak and low speed torque, fuel consumption and transient response.

Reliability and easy service access are integral to the design of the engines. It is available with a range of installation options to enable OEMs to minimise the size of the engine bay of their machines.

A lifetime of low cost

The fuel consumption is optimised to match the operating cycles of a wide range of off-highway machines. No additional fluids or additives are required which lowers operating costs and operator training.


Hydraulic tappets, multi-vee belts and long service intervals enable low cost maintenance

Dependable power

The engine has been designed using the latest predictive engineering methods, combined with an extensive field validation program to ensure reliable power in the toughest off-highway conditions.


Quality, reliability and consistency are assured. Our facilities worldwide employ the same efficient processes, the same tested and validated components, and the same stringent quality controls wherever your engines are manufactured.

Industry leading flexibility

A modular engine concept allows OEMs to design one engine installation for many different regions. This reduces cost and development time for cooling pack, mounting, hydraulic and control interfaces.
