How a GreenBoy engine is made.

Six stages, one standard. Keep scrolling to follow a unit down the line.

Design & Engineering01

Design & Engineering

Duty cycle, load profile and emission class defined up front, then engineered to CPCB IV+ limits.

Stage 1 / 6

Precision Machining02

Precision Machining

Blocks, heads and housings machined and inspected against drawing tolerances.

Stage 2 / 6

Assembly03

Assembly

Engines, alternators and canopies built up on the line at Sriperumbudur.

Stage 3 / 6

Dynamometer & Emission Testing04

Dynamometer & Emission Testing

Every unit load-tested and its exhaust measured before it leaves the floor.

Stage 4 / 6

Certification05

Certification

Type approval and conformity of production documented against CPCB norms.

Stage 5 / 6

Dispatch & Commissioning06
