A ceramic engine is an internal combustion engine made from specially engineered ceramic materials. Ceramic engines allow for the compression and expansion of gases at extremely high temperatures without loss of heat or engine damage. [1] Proof-of-concept ceramic engines were popularized by successful studies in the early 1980s and 1990s.
Over a period of time, Detroit Diesel continued to further evolve the design of the engine. They finally brought the engine up to 137.5 hp (102.5 kW) per cylinder and 406 lb⋅ft (550 N⋅m) torque per cylinder; needless to say, this is a considerable amount of power coming from 149 cu in (2.4 L) per cylinder.
To improve durability a new piston design using alumina-silica ceramic fiber reinforced piston ring grooves was used in place of the usual cast iron insert. This makes it one of the earliest applications of metal matrix composites. [73] [58] [74] Like the 2L-T, it is a turbocharged 2.4 L (2,446 cc) SOHC (single overhead cam) engine with 8 ...
Coatings used in modern motorcycles include chromium, [13] nitride, [14] or ceramic coating made by plasma deposition [15] or physical vapour deposition (PVD). [ 16 ] [ 17 ] Most modern diesel engines have top rings coated with a modified chromium coating (known as CKS or GDC), [ 13 ] [ dead link ] which has aluminium oxide or diamond ...

Bore: 3 1 ⁄ 4 inch (83 mm) Stroke: 4 inch (102 mm) Displacement: 3.261 L (200 cu in) Performance Power output: 105 bhp (78 kW) at 2,400 rpm Torque: 270 lb.ft at 1,200 rpm BMEP: 105 lb.sq.in Applications Trucks The TS3 was used in both the Commer and Karrier range of trucks. As the horizontal cylinders ...
They are generally diesel engines with combustion chamber parts lined with ceramic thermal barrier coatings. [13] Some make use of titanium pistons and other titanium parts due to its low thermal conductivity [14] and mass. Some designs are able to eliminate the use of a cooling system and associated parasitic losses altogether. [15]
Mitsubishi's new clean diesel engines use a 200 MPa (2,000 bar) high-pressure common rail injection system to improve combustion efficiency. The 4N13 1.8 L (1,798 cc) uses solenoid fuel-injectors. The larger 4N14 2.3 L (2,268 cc) engine uses piezo fuel-injectors that produce a finer fuel spray. Both engines feature a fast ceramic glowplug system.
A piston is a component of reciprocating engines. It is located in a cylinder and is made gas-tight by piston rings. Its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In two-stroke engines the piston also acts as a valve by covering and uncovering ports in the cylinder ...
