Maruti Celerio diesel engine (DDiS 125) validated for 4-5 lakh km

In a recent interview, C.V. Raman, engineering head, Maruti Suzuki, revealed that the company has tested and validated the Maruti Celerio diesel (DDiS 125 engine) for 4-5 lakh km in hot and cold temperatures, and high altitudes with all possible grades of diesel fuel available in India.

Celerio’s DDiS 125 is Maruti Suzuki’s first homegrown diesel engine.

The 793 cc twin-cylinder diesel motor generates 47 hp and 125 Nm of torque while delivering an ARAI certified mileage of 27.6 kmpl. Maruti’s Indian engineers were responsible for coming up with acceptable requirements and benchmarking while Suzuki’s Japan HQ took care of design and engineering aspects of the development.

Both entities worked jointly towards the localization of the engine in India. In terms of value, 97% of the engine is sourced in India with only a few specific elements like a casting component, timing chain, etc., are being imported.

The 793 cc mill is the smallest diesel unit to be employed in a production car.

The aluminium block engine gets a specially designed compact fuel injection system which employs a small block where fuel is stored at 1,400 bar of pressure before being distributed to the injectors. Since there are only two cylinders, a common rail system was not required to achieve the desired refinement and performance levels. The extremely small turbocharger was developed by Borgwarner.

Depending on the performance of Celerio diesel in the market, Maruti may choose to introduce the DDiS 125 in more passenger cars like Wagon R.
