Petrol engines

In such engines, petrol and less frequently alcohol-benzine and benzol mixtures are used. In the engine a compression occurs in cylinders of the mixture of petrol and air, which is ignited after the compression.

In 1990, at the request of the Director of the Center for Refining, Petrochemistry and Engineering at the Ecole Nationale Superieure du Petrole et des Moteurs, the late Jean Durandet initiated the conceptual foundations for the new series that he was unable to complete. We would like to pay a tribute to him here.

This is the main prime mover (PM) for the generator and may be a gas, petrol or diesel engine, depending upon the availability of fuel. In the discussions below, we emphasize a diesel engine, being used more commonly for captive power generation.

SC Service typical of petrol engines in 1964-1967 cars and trucks. Oils designed for this service provide control of high- and low-temperature deposits, wear, rust and corrosion. 

SF Service typical of petrol engines in cars and some trucks from 1980. Oils developed for this service provide better oxidation stability and anti-wear performance than SE oils. They also provide protection against engine deposits, rust and corrosion. Oils meeting SF may be used wherever SE, SD or SC is recommended. 

SG Service typical of petrol engines in present cars, vans and light trucks. Oils developed for this service provide improved control of engine deposits, oil oxidation and engine wear relative to oils developed for previous categories. Oils meeting SG may be used wherever SF, SE, SF/CC or SE/CC are recommended. 

The most common of the other specifications are those with the prefix MIL, issued by the US military authorities. M1L-L-2104E approximates to the API CE rating for diesel lubricants, although it also relates to petrol engines that require API SE performance. M1L-L-46152D covers oils for both diesel and petrol engines, and approximates to API SG/CC (Figure 52.5). 

Another important set of performance specifications is produced by the European Vehicle Manufacturers Association, known by its initials CCMC. The CCMC rating G-1 corresponds roughly to API SE, and G-2 to API SF. G-3 (comparable to M1L-L-46152B, for petrol engines only) covers fuel-efficient and light-viscosity lubricants... 

The deposits formed in internal combustion engines by high-octane petrols may be classed as ashes they consist of mixtures of lead oxides, bromides and sulphates derived from the anti-knock additives and, of course, exert their main corrosive effect on the parts operating at the highest temperature the exhaust valves and the sparking-plug electrodes. 

Steam, gas, petrol, and hot-air engines are heat engines a thermopile coupled with an electromotor also constitutes a heat engine. An electromotor is not a heat engine, since its effect is produced at the cost of electrical energy, which may, it is true, ultimately be derived from a heat engine coupled with a dynamo, but may equally well arise from chemical action in voltaic cells absorbing practically no heat from their environment (e.g., the Daniell cell). 

To meet Emission Standards, new 1991 models are designed to run on unleaded petrol, and therefore, new engines working at a higher compression ratio will be from 8 to 10% more efficient than older ones. 

An account is given of the Recopet process, jointly developed by Technochim Engineering and Institut Francais du Petrole, for the chemical recycling of PETP. The process, which consists of saponification, purification by chromatographic absorption and acidification, produces a terephthalic acid of high purity.

Potential sources of carbon monoxide hazards include metal-refining processes, in which it is formed as a byproduct and used as a fuel (LEL 12.5%), and running vehicle engines (particularly petrol-driven) or gas-fired heaters in poorly ventilated confined spaces. It is also a feedstock in the manufacture of a variety of chemicals, e.g. methanol, acetic acid, phosgene and oxo-alcohols. 

Engines. Vehicular petrol engines are potential ignition sources by means of the spark-ignition system, dynamo or battery, or hot exhaust pipe. Non-flameproof diesel engines are potential ignition sources due to a hot exhaust pipe or carbonaceous particles or flames from the exhaust.
