Ashok Leyland Produces New CNG Engine For Buses

Chennai: Ashok Leyland Ltd, has produced CNG engine for buses with multi-point fuel injection (MPFI) system that can meet Euro IV emission standards. The MPFI system will inject the gas at several points into the cylinder, progressively within infinitesimal fractions of a second. Consequently, fuel burns better in the MRFI engine and, hence, it delivers more power and torque, fuel efficiency and lower emissions than the existing carburettor engine. Currently, the company develops the ''H'' series 6E, six cylinder engine for CNG buses that give maximum power of 90 kW at 2,400 rpm. The new engine offers superior power rating at 135 kW at 2,400 rpm. The new ''H'' series CNG engine is the country''s first one-litre-per-cylinder in six cylinder configuration. The MPFI system delivers the required gas quantity at the intake manifold, as per the vehicle demand even in transient operating conditions
