The Application of Lag-Process in Prechamber Engines
SAE Technical Paper Series, 1979<div class="htmlview paragraph">The paper deals with the effect of some design and controlling parameters of a prechamber engine on combustion and operation. The lowest delay in the working mixture ignition, the highest rate and completeness of the burning, the widest stability limits for combustion of lean mixtures, the lowest octane ...

Prechamber Initiation of Gaseous Detonation in a Channel
Combustion Science and Technology, 2016ABSTRACTDeflagration-to-detonation transition in propane-butane-oxygen mixtures, in an open channel with a circular cross section with a diameter of 3 mm, was investigated experimentally. Detonation initiation was carried out by burning the mixture in the prechamber connected to the channel.

Volume 1: Large Bore Engines; Fuels; Advanced Combustion, 2018
Turbocharged gas engines for combined heat and power units are optimized to increase efficiency while observing and maintaining legitimate exhaust gas emissions. In order to do so, the charge motion is raised. This study investigates the influence of passive prechamber spark plugs in high turbulent combustion chambers. The subjects of investigation are

Prechamber for Lean Burn for Low NOx
SAE Technical Paper Series, 1995<div class="htmlview paragraph">To ignite very lean natural gas mixture it is necessary to use prechambers. The extension of lean limit of a combustion system is given by citing an example. The orifice diameter from the prechamber to the main chamber has a strong effect. The magnitude of the effect for one particular example is shown.

A Quasidimensional Model of SI Natural Gas Engines with Prechamber
SAE Technical Paper Series, 1997<div class="htmlview paragraph">Spark ignition natural gas engines with prechamber, having high thermal efficiency and low exhaust emissions, have been developed due to energy resources and air pollution problems in recent ten years. A lot of significant results on experimental have been given, but the reports on combustion model were few seen so

A Prechamber-type Compression Ingition Engine Operated by Composite Fuels
SAE Technical Paper Series, 1991<div class="htmlview paragraph">Reduction of soot and NOx emissions from a prechamber-type diesel engine is studied by employing both <i>chemical</i> and <i>physical</i> aspects of the fuel and induction method. Fuel modification was performed to produce several forms of composite fuel: solution of alcohol and gas oil (JIS

Investigation of a Lean-Burn Piston Engine with Catalytic Prechamber
SAE Technical Paper Series, 1996<div class="htmlview paragraph">Lean burning in piston engines gives opportunity to achieve important enviromental and fuel economy objectives. Unfortunately, lean mixtures are not readily ignited and are characterized by poor flame propagation. Thus, techniques which enhance ignition, flame formation and its propagation must be applied, if lean ...

Combustion System of a Lean-Burn Piston Engine with Catalytic Prechamber
SAE Technical Paper Series, 2001<div class="htmlview paragraph">In the present work it is proposed to improve the efficiency of an Otto engine by development of a system with assisted catalytic ignition and combustion. The system is characterized by the use of a lean mixture in a swirling charge, substantial increase of the compression ratio, and application of a catalytic ...
