Like a gas combustion engine, a hydrogen engine relies on the combustion process - in this case, combustion that results when hydrogen is combined with oxygen. Fuel cells in a hydrogen-powered car then convert this mechanical energy into electrical energy.

Generator and the batteries it charges.
All hybrids use a conventional engine.
Yes, Hybrid cars have both electric and combustion engines. In most cars the Combustion engine kicks in to charge the batteries to extend range before having to recharge and refuel.
Engines can be classified into five main categories: internal combustion engines, which burn fuel to create power; external combustion engines, where fuel is burned outside the engine, such as steam engines; electric engines, which convert electrical energy into mechanical energy; hybrid engines, combining internal combustion and electric power sources; and rocket engines, designed for propulsion in space by expelling mass at high velocity. Each type serves different applications and operates on distinct principles.
a standard combustion engine has rather negative effects on the environment today because of overuse of the combustion engine causes pulution in the earths atmosphere and causes the ozone layer to deplete. The new hybrid engines make a mazimum of 1/2 of the poulition of a regular combution engine because the hybrid engine runs off of the gasoline 4 cyl. combustion engine but charges the battery for the electric engine also. the electric engine powers the main accelleration of the car but eventully runs out of charge and automatically swithces over to the combutsion engine to power the car and charge the battery.

The difference between and hybrid and a standard car is simple, a hybrid uses two or more distinct power sources (internal combustion engine and an electric motor); non hybrids run solely on internal combustion engines. What makes hybrids stand out is the electrical engine inside. This electrical engine accepts many different power sources such as compressed air, hydrogen, liquid nitrogen , wind power, and solar power. Some models such as the Chevrolet Volt run solely on electricity.
Water hybrid vehicles still rely on gasoline as fuel. Water hybrid vehicles need an HHO, a hybrid hydrogen oxygen system. The HHO is a fuel cell that breaks water down into hydrogen and oxygen. Hydrogen gas is added to the gasoline to enhance combustion. When the hydrogen gas is ignited in the cylinders it converts back to water. Not only do water hybrid cars increase gas mileage, they clean out carbon from the exhaust gas.
Over the years, cars have had many kinds of engines: steam, gasoline, diesel, and electric. Most common are reciprocating internal combustion Engines. Most are 4-stroke gas/petrol engines. Some use LNG, some ethanol, some diesel. There have been 2-stroke motors, too. And some rotary engines: mostly Wankel, but also the occasional gas turbine. Steam engines were external combustion, with drawbacks in start-up and power output. Electric cars may use onboard generators, or batteries, or both (hybrid vehicles). Future cars may use electric fuel cells powered by hydrogen gas and compressed oxygen.
Yes, ammonia has been used as a propellant in rocket engines. It is valued for its high energy content and can be used in both liquid-fueled and hybrid rocket engines. However, it is less common than other propellants like liquid hydrogen or kerosene.
