Motors spark ignition

Dispersingagents, such as polyethylene polyamide succinimides or methacrylate-type copolymers, are added to motor oils to disperse low-temperature sludge formed in spark-ignition engines. 

LPG, stored as a liquid at its saturation pressure, is vaporized and introduced as vapor in conventional spark ignition motors. These motors are not modified with the exception of their feed system. Moreover, in the majority of cases, dual fuel capabilities have been adapted, that is, the vehicle can use either LPG or liquid fuel. 

The use of propane as a motor vehicle fuel has been highly developed in some countries, particularly in the USA, Holland and Italy. It is, of course, an entirely lead-free fuel. Very high efficiencies can be obtained using a gaseous fuel in spark-ignition engines since intimate mixing of the fuel and air is much more easily achieved than with a liquid fuel. This results in a much cleaner exhaust, with considerable reductions in CO and hydrocarbons. 

Motor octane method a test for determining the knock rating of fuels for use in spark-ignition engines see also Research octane method. 

Carbon disulfide, CS2, is an extremely volatile and flammable substance. It is so flammable that it can ignite when exposed to boiling water Because carbon disulfide vapour is more than twice as dense as air, it can "blanket" the floor of a laboratory. There have been cases where the spark from an electrical motor has ignited carbon disulfide vapour in a laboratory, causing considerable damage. For this reason, specially insulated electrical motors are required in laboratory refrigerators and equipment. 

Examples of the application of motored engines are discussed in Section 6.4 and 6.5. These have contributed significantly not only to the better understanding of the mechanisms of hydrocarbon oxidation but also to a bridging of the gap between the interpretation of reactions investigated in more conventional chemical systems, and the reactions of hydrocarbon fuels in spark-ignition engines. 

In the process of electrifying the automobile, the hydrogen FCV has no need for the internal combustion engine (ICE) or the oil it burns. Since their inventions in the late 1800s, spark ignition ICEs used to burn gasoline and compression ignition ICEs used to burn diesel have powered virtually all the billion plus motor vehicles built to date. ICEs are installed in virtually all the 50 million cars, trucks, and buses built annually around the world today. 

Special Duty Propane is intended for use in spark-ignition engines, and the specification includes a minimum motor octane number to ensure... 

Motor fuels are an important product. Gasoline is required for spark-ignition engines. The different needs of aircraft and vehicles are constrained by the different qualities of the fuels produced in the refineries. Aviation fuels demand a high octane. Other products are added to motor fuels to improve their performance in automobiles. 

Term used in the UK for a light hydrocarbon liquid fuel for spark-ignition internal combustion engines. Other terms for such fuel are gas(oline) and motor spirit. 

Lean burn, spark ignited, internal combustion (ic) engines especially as used in motor vehicles have received considerable attention during the past few years. The reasons for this are well known by comparison with stoichiometric or rich mixtures, lean mixtures produce a lower pollutant level and improved fuel economy. There are problems associated with lean burn, specifically the mixture is slow burning and hard to ignite. 

The influence of motor-specific parameters on the mass of PAH in the exhaust gas was investigated for three different spark ignition... 

The corpus, consisting of volumes A1 to A28, tackles more specialized subjects, classed in alphabetical order. An index allows appropriate articles to be found. For example, the article Motor Fuels (vol. A16, p. 719) treats spark-ignition engines and Diesel engines from different points of view technology, fuels, emissions. 

Internal combustion (IC) engines for motor vehicles are of two kinds spark ignition (SI) and compression ignition (diesel). The SI engines use gasoline, alcohol, or compressed natural gas fluids (propane) or compressed natural gas as fuel introduce the fuel to the cylinder by carburation or injection and use a spark plug for ignition. Diesel en-...

Motor Oils. Spark-ignition and diesel-engine oils differ primarily because the diesel oils must exhibit detergency properties to keep carbon from accumulating in the engine after a few hours of operation. Naphthene-base oils (low Viscosity Index) are somewhat satisfactory as diesel oils, but most heavy-duty oils are made by introducing a detergency additive to an oil manufactured from paraffin or mixed-base crude oils. 

A fuel additive used to minimize ice formation. Chemical compounds added to motor and aviation gasolines to improve fheir performance and to reduce knock in spark-ignition engines. 

Unlike spark-induced combustion engines requiring fuel that resists autoignition, diesel engines require motor fuels, for vhich the reference compound is cetane, that are capable of auto-igniting easily. Additives improving the cetane number will promote the oxidation of paraffins. The only compound used is ethyl-2-hexyl nitrate.
