Analysis of some design for both compression ignition and spark ignition engines which give improvement from point of view fuel efficiency and pollutant emission including CO2 are presented in the paper. Actual and future standards requirement for pollutant emissions and CO2 as well test procedures, generally for light duty car for Californian standards and European standards are overviedwed. Especially common rail system for compression ignition and spark ignition engines were presented. Air assist system which can be applied for four stroke and two stroke engines was described too. Gasoline direct injection system which operate in 2 modes: lean burn mixture when engine run with a part load and homogeneous charge with stoichiometric mixture when engine run with high load is presented. Lean stratified mixture is realized as a late fuel injection during compression stroke but homogenous charge is realized as a early fuel injection during induction stroke. Lean mixtures require to apply special de - NOx catalytyst which joined with three way catalytyst (TWC) enable meet of standard requirements concerning exhaust emission. Investigation concerning some solutions of mixture preparation process and combustion were conducted. Mixture preparation process investigations were conducted with laser Doppler equipment LDV (3D) and PDPA. Combustion processes ware conducted in constant volume chamber. During combustion process testing the flow field, fuel droplet dimension and structure of fuel spray profitable for ignition process close to spark plug was determined. If velocity of the droplet in spark plug was near zero and droplet dimension were small repeatable ignition for lean mixture was obtained.
