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.
Do petrol engines produce more CO than diesls?
Yes, petrol engines generally produce more carbon monoxide (CO) than diesel engines. This is primarily due to the combustion process; petrol engines often operate at lower temperatures and can produce incomplete combustion, leading to higher CO emissions. In contrast, diesel engines operate at higher temperatures and pressures, which typically results in more complete combustion and lower CO emissions. However, diesel engines tend to emit higher levels of nitrogen oxides and particulate matter.
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.
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.
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 type of engines do motorcycles have?
Motorcycles typically have internal combustion engines, which can be classified into two main types: two-stroke and four-stroke engines. Two-stroke engines are lighter and simpler but generally less fuel-efficient and produce more emissions. Four-stroke engines are more common in modern motorcycles, offering better fuel efficiency, lower emissions, and greater durability. Additionally, some motorcycles use electric motors, particularly in electric models, providing an alternative to traditional combustion 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.
