What are the different types of diesel engines are there?
In a nutshell, you have highway engines, off-road engines, marine engines, and power generation engines. While the different types might be built on matching blocks, where they're cruised at RPM-wise, the amount of power they produce, and their peak powerbands will vary, as well as the emissions standards which they're subject to.

What are the differences between a 4-cycle and a 2-cycle engine in terms of performance and efficiency?
A 4-cycle engine has four stages (intake, compression, power, exhaust) in one cycle, while a 2-cycle engine has only two stages (combustion and exhaust). 4-cycle engines typically have better fuel efficiency and lower emissions, but 2-cycle engines are simpler and can produce more power for their size.
Can a engines power be increased while at the same time decreasing its emissions?
Yes, A poorly tuned engine will produce more emissions and less power than a well tuned engine.
Why thus the compression ignition engines produce fewer emissions?
Compression ignition engines can easier be made to run lean, meaning they'll havemore air than what's actually needed for the amount of fuel that's present. With excess air,(and higher temperature) it's easier to get more of the fuel burnt. With more of the fuel burnt, there's less unburnt fuel being vented as exhaust, meaning fewer emissions.
How can a designer of solid rocket engines make the engines produce different amounts of thrust?
The thrust of a solid rocket engine depends on the composition of the solid fuel and the rate at which it is burned, and to some extent on the way the gases are directed by the exhaust nozzles. The same material can be burned at different rates to produce more or less thrust, and the nozzles (also used for directional control) can divert this thrust to control velocity and stability.
What is emissions systems?
The emissions system used in cars is a system which is designed to restrict the amount of pollution cars produce. Newer cars have system which prevent both Evaporative Emissions and harmful Exhaust Emissions. The Evaporative Emissions (EVAP) system prevents the escape of unburnt fuel vapor form the fuel tank, the fuel lines, and the engine. The Exhaust system uses at least one Catalytic converter, which is used to burn off gasses produced by the engine. On newer cars, both the EVAP and Exhaust are monitored by the vehicle's computer, which can alter the way the engine runs and can warn the driver of EVAP leaks.
Why petrol engines produce oxides of nitrogen?
Petrol engines produce oxides of nitrogen (NOx) as a byproduct of combustion at high temperatures. Specifically, nitrogen in the air reacts with oxygen in the engine's combustion chamber to form NOx gases. Factors such as high compression ratios and combustion temperatures can contribute to increased NOx emissions from petrol engines.
What part of the plane produces thrust?
The engines of the plane produce thrust by expelling a high-velocity stream of air or exhaust gases backwards. This thrust propels the aircraft forward and allows it to move through the air.
What does cars produce?

How can a Designer of solid rocket engines make engines produce different amounts of thrust?
The thrust of a solid rocket engine depends on 3 different values. The first is the rate at which the solid fuel is burned, the second is the composition of the fuel itself, and the third is the way the gas that is coming from the engine is directed by the exhaust nozzles. Therefore as one can see, the exact same material can be burned at very different rates, depending on how much thrust it is producing. So the designer only has to control and slightly change the exhaust nozzles to change the amount of thrust produced by the engine.
