The power developed by an engine at the output shaft is called brake power and is given by **Power = NT/60,000 in kW where T= torque in Nm = WR W = 9.81 * Net mass applied in kg**.

## What is brake power of a diesel engine?

**the power actually delivered by the engine and is therefore the capacity of the engine**. The power developed in the combustion chambers of the engine is greater than the delivered power because of friction and other mechanical losses.

## How do you calculate the indicated power of a diesel engine?

…

**The power produced by each cylinder unit is given by P*L*A*N *2* π /60 kw., where :**

- P is the mean effective pressure given in KN/M. …
- L is the length of stroke given in.
- A is the area of bore of each cylinder given in M
^{2}. - N IS the RPM measured from counter readings .

## How do you solve break power?

1. **BHP = (Torque × RPM )/5252**,where torque is lb -ft and n = revolution per min.

## How can brake power of diesel engine increase?

**increasing the pressure of intake air**.

## Why Do They Call It BHP?

This is a French acronym, standing for chevaux-vapeur. bhp — **brake horsepower** is a term you may be familiar with, particularly if you read a lot of UK car magazines. More to come on this one. kW — this stands for kilowatt and, in terms of cars, is used most commonly in Europe for electric car power outputs.

## What is a Morse test?

The purpose of Morse Test is **to obtain the approximate Indicated Power of a Multi-cylinder Engine**. It consists of running the engine against a dynamometer at a particular speed, cutting out the firing of each cylinder in turn and noting the fall in BP each time while maintaining the speed constant.

## What is brake thermal efficiency?

Brake. thermal efficiency is **the ratio of energy in the brake power to**. **the fuel energy**.

## What is the last stroke of two stroke cycle engine?

In a two-stroke engine, the end of the **combustion stroke** and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time.

## What is Imep?

This is generally expressed as the indicated mean effective pressure (IMEP) and is **a measure of the work output for the swept volume of the engine**. The result is a fundamental parameter for determining engine efficiency as it is independent of speed, number of cylinders, and displacement of the engine.

## What is the percentage of heat loss through the exhaust system in a naturally aspirated passenger car operate on gasoline?

Heat losses are by far the largest losses in the engine, with roughly **60%** of the energy from the fuel lost to heat; about half of that heat is lost to the cooling system and the other half to the exhaust.

## What does volumetric efficiency measure?

1 Volumetric Efficiency. The volumetric efficiency represents **the efficiency of a compressor cylinder to compress gas**. It may be defined as the ratio of the volume of gas actually delivered to the piston displacement, corrected to suction temperature and pressure.

## How fast is one horsepower in mph?

More precisely, 1 HP equals **0.3-1.3 mph** for vessels like smaller boats and jet skis, 0.6-1.2 mph for average cars and UTVs, 0.8-1.6 mph for most heavy and middleweight motorcycles, and 3-10 mph for lightweight motorcycles.

## What is the brake power?

Brake power means **the usable power output of the engine, not including power required to fuel, lubricate, or heat the engine, circulate coolant to the engine, or to operate aftertreatment devices**.

## What is heat balance sheet?

A heat balance sheet is **an account of heat supplied and heat utilized in various ways in the system**. Necessary information concerning the performance of the engine is obtained from the heat balance. The performance of an engine is generally given by a heat balance sheet.

## What is frictional power?

The friction power is defined as **the difference**. **between the power delivered to the piston while**. **the working fluid is contained within the cylinder,** **and the usable work delivered to the drive shaft**.

## Is there a 3 stroke engine?

**A three-stroke internal combustion engine** completes a complete combustion cycle of exhaust, intake, compression, ignition, and expansion within a single revolution of a crankshaft by a single stroke of a first piston and a single stroke of a second piston within a single cylinder.

## Can you run diesel in a 2-stroke engine?

In general, **it’s OK to add 2 stroke oil to diesel fuel for extra lubricity**, but it’s far easier and… Some diesel owners like to add a little 2-stroke oil to their fuel tank to lubricate the fuel system and upper end of the cylinders. Sometimes, people use regular motor oil, too.

## How do I find my BMEP?

**BMEP = (Torque x 75.4) / (Displacement x PPR)**

It is also clear that because the equation includes PPR ( Power Pulses per Revolution ), it applies to engines with any number of cylinders by using the total displacement, total brake torque, and correct PPR.

## Is diesel exhaust worse than gas?

The simple answer is **diesel emits slightly more pollutants per gallon than gasoline does**.
