Lean burn

Lean burn is an internal combustion of lean air-fuel mixtures. It happens at very high air-fuel ratio (up to 65:1), so the mixture has considerably less amount of fuel in comparison to stoichiometric combustion ratio (14.6:1 for petrol).

The engines designed for lean burning can employ higher compression ratios and thus provide better performance, efficient fuel use and low exhaust emissions than those found in conventional petrol engines. Ultra lean mixtures with very high air-fuel ratios can only be achieved by Direct Injection engines.

The main drawback of lean burning is the large amount of NOx being generated, so a complex catalytic converter system is required.
