Work indicated in engines refers to the theoretical work output calculated from the pressure and volume changes during the combustion process, typically measured by an indicator diagram. Brake work, on the other hand, is the actual useful work output of the engine that can be harnessed to perform tasks, measured at the output shaft after accounting for losses due to friction, heat, and other factors. The difference between the two represents the engine's efficiency and losses in converting the indicated work into usable power.

How does a Jake brake work?

the Jake brake and similar brakes redirects the engines exhaust, using the resulting compression to slow the cylinders of the engine which cuts the rpm dtrastically, therefore slowing the vehicle.


Can brake cleaner be used as starter fluid for engines?

No, brake cleaner should not be used as starter fluid for engines. Brake cleaner is not designed for this purpose and can be dangerous if used incorrectly. It is important to use the appropriate starter fluid for engines to ensure safe and effective operation.

What is the best way to use brake cleaner as a starting fluid for engines?

It is not recommended to use brake cleaner as a starting fluid for engines. Brake cleaner is not designed for this purpose and can be dangerous if used incorrectly. It is best to use a proper starting fluid that is specifically designed for engines to avoid any potential risks or damage.


What is brake power in diesel?

Brake power (BP) in diesel engines refers to the actual power output available at the engine's crankshaft, measured in horsepower or kilowatts. It is determined by the engine's ability to perform work, taking into account losses due to friction and other factors. BP is typically measured using a dynamometer and is a critical parameter for evaluating engine performance and efficiency. Unlike indicated power, which reflects the total power developed from combustion, brake power represents the usable power delivered to the drivetrain or machinery.

indicated power is maximum out put power of the engine brake power is the... brake power =T*W T=torque W= angular velocity of wheel indcated power =BHP+Friction. Mechanical Efficiency :- BHP/IHP


What kind of braking system uses a brake booster?

Brake boosters are found on car braking systems, to help the brakes to stop the car. They work on the disc brakes, using a vacuum supply to add to the hydraulic braking system. On petrol engines the engine may provide the vacuum, on diesel engines there needs to be a separate pump.


What are the differences between brake cleaner and starting fluid, and how do they compare in terms of their effectiveness for cleaning and starting purposes?

Brake cleaner is designed to remove dirt and grime from brake components, while starting fluid is used to help start engines in cold weather. Brake cleaner is not recommended for starting engines, as it can be harmful if ingested. Starting fluid is specifically designed to help start engines and should not be used for cleaning purposes. In terms of effectiveness, brake cleaner is better for cleaning brake components, while starting fluid is more effective for starting engines in cold weather.


Can brake cleaner be used as starting fluid for engines?

No, brake cleaner should not be used as starting fluid for engines. Brake cleaner is not designed for this purpose and can be harmful to the engine. It is important to use the correct type of starting fluid recommended by the manufacturer for safe and effective engine starting.

What is difference indicated power and brake power?

In an engine, indicated power is the power produced in the cylinder and the brake power is the useful power at the output shaft. Brake power is always less than indicative, due to losses by mechanical friction and parasitic loads (oil pump, air conditioner compressor, etc...) The two are related by (mechanical efficiency) = (brake power) / (indicative power)
