The family of engines strategy uses a common power cylinder system across several different engine variants to address a range of power and torque requirements in order to serve multiple military vehicles with a common architecture. The variable flow lube pump helps maintain engine efficiency.
A collaboration between research teams at Shell and Gordon Murray Design (GMD) recently led to the development of an innovative conceptengine lubricant capable of achieving a 6.5% 25 city car as the test bed, Shell engineers formulated an ultra low viscosity 0W-10 motor oil. benefit on a combined cycle.
Oil-less carbon-air bearing system. Bladon suggests that in an hybrid vehicle application, with no water-cooling system, oil or catalytic converter, the Micro-Jet engine can provide vehicle weight savings of up to 15%—with a consequent reduction in fuel consumption and carbon emissions—compared to a piston engine.
The ETI is a public-private partnership between global energy and engineering companies—BP, Caterpillar, EDF, E.ON, Rolls-Royce and Shell—and the UK Government. This project will look to improve the overall system design, with a synergistic focus on gears, bearings, surface treatments, lubricant flow and lubricant composition.
The piston assembly slides rigidly through the block via an oil pressure fed guiding system eliminating piston to cylinder-bore contact, reducing wear and lubrication requirements in the cylinder, and also reducing piston side shock—making ceramic technology suitable. Tags: ConceptEnginesEngines.
The X2 engine is less sensitive to prototyping/machining errors, and is very fast to assemble and disassemble, so ultimately it will improve our development time, Shkolnik said. The X2 engine is planned to be available as a beta prototype for outside testing by the first quarter of 2013.
Mpa (8 bar) and the oil flow rate is 3L/min. For the study, Honda installed a small pump separate from that of engine lubricating oil pump. Oil passage was constructed from the external pump through the crankshaft and connecting rod to the piston. Tags: ConceptEnginesEngines. Ishikawa, K.
Since internal combustion engines will remain the primary mode of choice for mobility in the foreseeable future, both alternative (renewable) fuels and high-performance combustion concepts/ engines using fuels adapted for that purpose will be preferred for reducing the combustion impact on climate change.
The technology to retrofit a vessel to accept methanol as a fuel is available today and the intention is for OCI to charter the first retrofitted methanol-fueled vessel operated by EPS using already in-service MAN engines and technology in the next two years. Components and pipes added to each cylinder to enable methanol fuel.
Oil is kept away from center of crank shaft by inertia and centrifugal force. Exhaust valve management allows the engine to independently configure (Intake Compression) to (Power Exhaust) ratios. Tags: ConceptEnginesEngines Fuel Efficiency.
