A typical method frequently used for the experimental investigation of engines operation at light load, low speed and different air-fuel ratios by spark timing adjustment was applied to understand in what measure the characteristics of the ignition s

Laser ignition was used to operate a four-stroke, four-cylinder, multipoint fuel injection gasoline passenger car engine, replacing the engine classical ignition device. The laser ignition system was compactly built with diode end-pumped Nd:YAG/Cr4+:

Characteristics of fuel-air mixture combustion in a naturally aspired spark-ignition engine with indirect injection that was ignited by classical spark plug as well as by laser sparks are presented. Differences between the duration of combustion, def

A Renault vehicle with gasoline indirect injection engine was fully operated with laser spark plugs that were build using high-peak power passively Q-switched Nd:YAG/Cr4+:YAG lasers. Some performances of the engine, including cycling variability, spe

A passively Q-switched Nd:YAG/Cr4+:YAG laser is used to investigate the air breakdown in a static chamber. The characteristics of the transmitted laser pulse are measured and the energy transfer from the pulses to plasma is evaluated. As the air pres

An electronic electroscope with a special design for demonstrations and experiments on static electricity is described. It operates as an electric charge sniffer by detecting slightly charged objects when they are brought to the front of its sensing

Proportional-integral-derivative (PID) controllers are widely used in process control, and consequently they are described in most of the textbooks on automatic control. However, rather than presenting the overall design process, the examples given i

We report on scaling of a laser configuration in which a YAG prism is used to couple the pump beam from a fiber-coupled diode laser directly into a Nd:YAG medium. Several resonator geometries have been investigated. In free generation regime laser pu

High-peak power passively Q-switched Nd:YAG/Cr4+:YAG lasers were employed to operate the engine of a Renault automobile. Improved engine stability and decreased CO and HC emissions were measured in comparison with ignition by electrical spark plugs.
