30. COMMONALITY OF PARTS
Common working parts right from 3
Cylinder to 6 Cylinder.
Less spares to store for user.
INDIVIDUAL CYLINDER HEADS
Easy Maintenance and greatly reduced
engine down times.
Reduced spare cost while replacing.
DEEP SKIRTED CRANK CASE
Gives rigidity and Stability to the design of
the engine.
INDEPENDENT FAN MOUNTING
Fan is mounted independent of the water pump.
Enables total flexibility in fan positioning.
INTEGRAL PLATE TYPE OIL COOLER
Cartridge type Integral Oil cooler. Lesser connections.
Leakage Eliminated
INTERNAL GEAR DRIVEN WATER PUMP
Eliminates a failure avenue in the engine.
TWIN BELT DRIVE FOR FAN
Two belts drive the fan. Ensures extra safety.
Engine runs even if one belt fails.
AUTOMOTIVE GRADE GEAR TRAIN
Ensure that this engine has the most silent sound map
among all competition.
