gas engines go faster that the batter powered engines and last longer (dont have to charge gas)
Good on gas, not much power unless turbocharged.
Some of the advantages of LPG (Liquefied Petroleum Gas) are smoother ignition, reduced engine noise, reduced engine wear and tear and improved combustion. It also provides a cleaner emission level and is better for the environment.
The basic advantage of a cam is that it could dispense with having to recirculate exhaust gas through EGR systems.
what are the advantages and disadvantages of s.i engine
A gas turbine engine will usually yield more power by weight than a piston engine. Main downside is that it can't be throttled very well. Energy efficiency isn't all that good to start with, and will drop right down if it has to be operated outside its optimum range.
The advantages of cars powered by natural gas are: They create a lot of energy with not much gas.
The advantage is that electric cars don't pollute and doesn't use fuel (gas, diesel, etc). But the thing is it can't go the distance of a gas engine or a hybrid.
Explain the advantages of four-stroke engine over two-stroke engine
The advantages of having dual exhaust, if it is a true dual exhaust, include increased gas mileage, cooler engine temperature, and more engine horsepower. However, if it is not a true dual exhaust, it doesn't matter how many exhaust ports there are, there will be no advantage.
Advantages of a GDI engine (a direct injection engine) include reduced fuel consumption, and performance boost.
A gas only engine has a spout where oil is added to the engine. If there is no spout, then it is a gas/oil engine. FYI - gas only engine is a four-stroke (four-cycle) engine and the gas/oil engine is two-stroke (two-cycle).
No gas in the engine
