Controlling Lead Exposure During the Process of Cleaning Aviation Spark Plugs
… process of removing lead bromide from aircraft spark plugs and the health hazards associated with the present method of cleaning the lead bromide accumulation from aviation spark plugs. Aviation maintenance technicians can be inadvertently exposed to lead while cleaning the lead bromide …

The effect of negligence and misadjustment on the automotive engine
… five degrees of that recommended; (5) the use of spark plugs which had been run a larger mileage than that recommended by the manufacturer; and (6) a change of the distributor breaker point gap within 0.007" limits of that recommended by the manufacturer. Restricting the air supply to the engine …

Laser ignition for internal combustion engines via fiber optic delivery
… of these are based on traditional electric arc spark plugs. Laser ignition represents a fundamentally different approach to igniting gas mixtures and opens the door to improvements in fuel-lean engine operation and high-pressure combustion environments. Yet the promise of laser ignition remains …

Study of an internal combustion engine to burn hydrogen fuel and backfire elimination using a carburetor fuel delivery method
… less expensive methods, such as employing cold spark plugs with reduced spark gap and low temperature cooled valves along with the introduction of water vapor to the mixture. In the experiments, the internal combustion engine was tested for two fuels: (i) octane 95 gasoline, and (ii) gaseous …

Improving the Efficiency of Gas Engines using Pre-chamber Ignition
… emissions. Initial experiments using pre-chamber spark plugs without auxiliary fueling showed improvements in combustion stability, but with only a marginal extension in the dilution limit with excess air and EGR; and hence no significant fuel efficiency improvements. Following these observations, …

Experimental and theoretical studies of combustion rates at high pressure
… of two flame kernels that originated at spark plugs mounted near the wall. It enabled the later stages of burning at the high pressures to be observed and burning velocities to be measured. The first method depended on highspeed schlieren photographic measurements of the flame speed, dr / …

Multihole injectors for direct-injection gasoline engines
… Equipment (FIE) for Direct-Injection (DI) Spark Ignition (SI) gasoline engines. Having explored thoroughly swirl pressure atomisers and their spray behaviour, multi-hole nozzles represent the second-generation injectors. Thus, complete investigation of multi-hole nozzle flow, spray …
