Answer 2

The four-cylinder diesel engine running at 2000 rpm improves the efficiency of the 60 kW brakes by 30% and the calorific value of the fuel CV is 42 MJ / kg, the engine has a 120 mm bore and a stroke 100 mm and takes = 1.15 kg / m * 3, air fuel pressure = 15: 1 and nm = 0.8 are:

• Available on most diesel-powered vessels of all kinds, the Four-Stroke Diesel Engine is a type of engine named because it requires the piston to eliminate four strokes while turning the crankshaft for internal combustion.

• The camshaft of the 4 stroke Diesel engine running at 1000 rpm will run on Automobile Engineering 500 rpm 1000 rpm 2000 rpm.

• The engine produces 3.68 kW of brakes.

• Its optimal operating efficiency is 30%, mechanical efficiency is 80%, calorific value of fuel is 42 MJ / kg and gravity is 0.875.

• A single cylinder standing engine has a bore of 120 mm and a stroke of 100 mm.

• The connecting rod is 1 m long and the weight of the replacement parts is 140 kg.

• In the expansion stroke, with a crank 30 ° from the high dead surface, the gas pressure is 0.7 MPa.

• Fuel-to-air measurements are simply crosses of air-to-fuel measurements: (F / A) molar = 1 / (A / F) molar = 1 / 2.38 = 0.420 kmol H 2 / kmol air (F / A) mas = 1 / (A / F) weight = 1 / 34.3 = 0.029 kg H 2 / kg air the stoichiometric fuel-to-air ratio does not change with a particular fuel.
