(mechanical engineering)
Ratio between the energy supplied to an engine to the energy output of the engine.

engine efficiency

engine efficiency
Propulsive efficiency of various types of jet engines.
The ratio of the propulsive power developed to the fuel power consumed. Specific fuel consumption (SFC) is one of the measures of engine efficiency.

The new product comes with a three-pronged technology that will greatly enhance engine efficiency by preventing oxidation sedimentation, as well as protecting valve-moving units and reducing fuel consumption.
A central message at the event was that the internal combustion engine is here to stay, efforts to cut global emissions must focus on increasing the fuel efficiency: With hydrocarbons - whether fossil or renewable based - meeting 99 per cent of the world's transport needs, Aramco outlined the importance of the company's work on greater engine efficiency and new technical advances enabling the onboard capture and storage of carbon.
Tensioners balance chain tension and optimise control over the entire engine operating range for increased engine efficiency and lower noise, vibration and harshness.
Designed to reduce mass, friction and noise, BorgWarners engine timing systems deliver greater durability, engine efficiency and fuel economy.
Octane index studies are important from a fuel formulation and engine operating condition perspective but do not directly address fuel consumption, engine efficiency or engine design changes which are important factors in order to connect with end-user (driver) perception.
Late combustion phasing is the consequence, leading to significant losses in engine efficiency.
Internal combustion engine efficiency has improved significantly over recent years, but higher efficiencies have permitted drivers to get the same consumption with larger engines.
The valves and gears are products that automatically advance or delay timing to adjust air flow in the engine cylinders, improving engine efficiency across a broader operating range.
S, source said to Research Analyst-PAGE that Minister for Petroleum and Natural Resources, Shahid Khaqan Abbasi gave a detailed briefing to the ECC on the usage of RON 92 gasoline in Pakistan and stated that it may be slightly expensive as compared to RON 87 but it would have benefits of mileage, engine efficiency, and environment friendly.
This enables the engine to operate on the lean-burn principle which increases engine efficiency and reduces peak temperatures - cutting Nitrogen Oxide emissions.
The complex has the latest equipment for maintenance and overhaul engines, in addition to a motor test unit to ensure engine efficiency and operational safety.
