1B engines operate according to most advanced direct injection procedure. It brings excellent exhaust quality and enables 1B engines to comply with EPA Phase 2 Emission Regulations in the USA.

1B engines are adopted SCS(Single Cam System) which is essential for the engine's short length. The detailes integrated to form a whole, 1B engines are compact and lightweight with reference to the power ratings.

1B engines equip sophisticated automatic decompression which is installed in the camshaft gear wheel and utilizes the centrifugal force and gravitation to facilitate an easy start without return shock. It functions down to a temperature of approx,-6 degreeC.

1B engines have various prepared additional equipment. It is easy to install and adapt to the requirement of every application.
