Ceramic Engine Pistons

In the engine s bottom end dry film lubricants are usually applied to piston skirts engine bearings and the main and rod journals.

Ceramic engine pistons.

The coating protects the piston skirt from heat friction and wear resulting in a reduction of parasitic drag while decreasing heat saturation into the piston skirt. But it s kind of a six because every cylinder has two pistons in it. This is an achates power opposed piston engine. Piston coatings are no longer the space age snake oils that mystified engine builders a few decades ago.

Polydyn rp piston skirt coating is a ceramic reinforced dry film lubricant with a low affinity for oil. Only isuzu has been a working engine an. The pistons move back and. First developed in the aerospace industry coatings suffered a tarnished reputation in the early days of automotive use as racers claimed they often flaked off the metal parts they were presumed to protect.

I have an invention in i c engine that can make use of ceramic cylinder blocks. C lube dry film ceramic lubricant combines the durability of a ceramic resin with the lubricity of a ceramic lubricant. C lube is a thermally cured dry film lubricant designed to provide high pressure lubrication to surfaces subject to sliding rotating or oscillating motion such as piston skirts and gears. Ceramic coated pistons can assist higher fuel burning efficiency and reduced carbon accumulation which in turn makes detonation more effective.

Coated piston skirts provide a dry sliding surface for engine startup and feature increased resistance to abrasion and scratching while moving within the engine block. As celle van giel has answered that i c engines employing ceramic cylinder block are on the test beds of reputed manufacturers. What this actually is is a 2 7 liter three cylinder. The coating is also designed to aid in the more even transfer of heat reducing hot.

Interest in and experimentation with ceramics in the internal combustion engine ice goes way back. Here is an article on the prospects for an adiabatic turbo diesel from 1987 adiabatic diesel engine technology in future transportation. Diesel internal combustion engine along with the revolutionary nr 1 supermileage vehicle deliver an unmatched fuel mileage of 200 mpg. It s often said the internal combustion engines which hold a special love hate place in our heart are basically air pumps and while that s a useful mental model when considering many aspects of how they operate it s more accurate to say.
