Summary:

A direct injection spark ignition (DISI) gasoline engine with a new stratified charge combustion concept has been launched on the Japanese domestic market. This new concept consists of two components. First, a thin fan-shaped spray from a slit nozzle enables wide spray dispersion, moderate spray penetration and a fine atomization. Second, a shell-shaped piston cavity allows better mixture formation, however avoiding distinct charge motions (such as tumble or swirl). Simple intake port geometry increases the full load performance. The combustion concept, at the same time allows stratified charge to be used at higher load and at higher engine speeds and improves the homogeneous charge combustion. A new 3L in-line 6 gasoline engine with this combustion concept showed 20% better fuel economy than a 3L port fuel injection (PFI) engine (λ=1 feed back system) under the Japanese 10-15 mode
