ECONOMICAL RUNNING
The direct injection system using the newly developped micro fuel injection pump assures superior combustions efficiency and minimized fuel consumption.

SMALL AND LIGHTWEIGHT
The newly developed micro fuel injection pump and crankcase structure originated in the gasoline engine have minimized the size and weight of the engine.

EXTREMELY QUIET OPERATION
The precisely synchronized fuel injection and refined combustion chamber allow lower combustion pressure which results in reduced combustion noise.
Blower housing is made from "DUMPING SHEET" a special material for insulating noise and vibration.
Larger super silent muffler and silent double element air cleaner reduce the exhaust and intake noise.

LESS VIBRATION
In addition to the reduced weight of reciprocating parts, a balancer shaft has been adopted for extremely smooth running with less vibration.
The automatic decompressor prevents shaky vibrations at stopping.

HIGH PERFORMANCE
Die-cast cylinder head generates a stable swirl of air-fuel mixture which results in the high output power and an exceptional fuel economy.
Its flat torque charracteristic provides tenacious running from slow speed to high speed.

SUPER RELIABILITY 
The advanced Robin technology, such as well proven crankcase design, tension bolt system for installing cylinder head, and forced lubrication system, for longer service life under the toughest operating conditions.

EASY STARTING
Light pull recoil starter and centrifugal automatic decompressor.
Automatic air-bleeder for the fuel system.
Auxiliary fuel inlet for easy starting in cold weather.

WIDE RANGE OF APPLICATIONS
Robin's new air-cooled diesel engine series assures maximum adaptability to any application.
Direct output type (D type) and reduction type (B type) are available.
Variable muffler exhaust direction.
Recoil starter and optional electric starter.
Strong power from small and lightweight body.
Lower noise and less vibration.
