The phrase "inefficient combustion" is grammatically correct and can be used in written English.
It is typically used to describe a process or situation where fuel is not being burned or converted into energy effectively. Example: The car's engine was running rough due to inefficient combustion, causing a decrease in fuel efficiency.
These problems arise when people cook in poorly ventilated indoor spaces using inefficient combustion technologies.
Marais, E. A. & Wiedinmyer, C. Air quality impact of diffuse and inefficient combustion emissions in Africa (DICE-Africa).
Carbon monoxide is the unwanted repository of considerable combustion energy in inefficient combustion systems.
Much of this is the result of the inefficient combustion of solid fuels on inefficient stoves in poorly ventilated homes and the widespread use of cars.
The emissions from this form of inefficient combustion are a significant contributor to human morbidity and mortality worldwide.
In contrast, reducing emissions of the sooty particles known as black carbon, which are given off by inefficient combustion in cooking fires and brick kilns, and by dodgy diesel engines, offers rapid, huge and tangible public-health benefits (see article).
Cooking with unsustainably harvested biomass can affect climate because inefficient fuel combustion releases products of incomplete combustion with a higher global warming potential than carbon dioxide, such as methane and carbon monoxide (Sagar and Kartha 2007).
But given all of that, the Clarity and its competitors from Toyota, GM, and several Chinese automakers are likely to win the long term battle for the next technology to replace burning oil in inefficient internal combustion engines as our primary form of getting from A to B. Waste: A thing of the past.
To replace the world's most energy-efficient machine, bar none with the polluting, inefficient internal combustion engine dependent on oil from the war-torn Middle East.
For the next few years, about half a dozen people explored whether there might be a better way to get to space than rockets powered by loud, inefficient chemical combustion.
This is an energy sector problem, as energy production and use, mostly from unregulated, poorly regulated or inefficient fuel combustion, are the most important sources of air pollution from human activity.
