𝗣𝗗𝗙 | On Jul 23, , Vishal Jagadale and others published Six Stroke Engine. PDF | One of the most difficult challenges in engine technology today is the urgent need to increase engine thermal efficiency. Higher efficiencies mean less fuel. PDF | In six stroke engine, there are additional two strokes, namely another power and exhaust strokes. The engine works through harnessing wasted heat.

Internal Combustion Engine while maintaining its prime focus on six stroke stroke the engine captures the exhausted heat from the four stroke cycle and uses.

A Seminar On SIX STROKE ENGINE By dovolena-na-lodi.infoh Abhay Chaudhari In WORKING OF VELOZETA SIX STROKE ENGINE The detailed working of .. 3) (International Journal.

The compression ratio is high for the heating chamber, which operates on an external cycle and is supplied solely with pure air.

Six-stroke engine

On the other hand, the compression ratio is low for the combustion chamber because of effectively increased volumen, which operates on internal combustion cycle. The combustion of all injected fuel is insured, first, by the supply of preheated pure air in the combustion chamber, then, by the glowing walls of the chamber, which acts as multiple spark plugs.

In order to facilitate cold starts, the combustion chamber is fitted with a heater plug glow plug. In contrast to a diesel engine, which requires a heavy construction, this multi-fuel engine, which can also use diesel fuel, may be built in a much lighter fashion than that of a gas engine, especially in the case of all moving parts.

As well as regulating the intake and exhaust strokes, the valves of the heating and the combustion chambers allow significantly additional adjustments for improving efficiency and reducing noise. The compression ratios can be increased because of the absent of hot spots and the rate of change in volume during the critical combustion period is less than in a Four stroke.

The absence of valves within the combustion chamber allows considerable design freedom. The specific power of the six-stroke engine will not be less than that of a four-stroke petrol engine, the increase in thermal efficiency compensating for the issue due to the two additional strokes.

This lead to very smooth operation at low speed without any significant effects on consumption and the emission of pollutants, the combustion not being affected by the engine speed. These advantages are very important in improving the performance of car in town traffic.

Multifuel: Multifuel par excellence, it can use the most varied fuels, of any origin fossil or vegetable , from diesel to L. The difference in inflammability or antiknock rating does not present any problem in combustion.

Methanol-petrol mixture is also recommended. Only improvements of the current technology can help it progress within reasonable time and financial limits. The six-stroke engine fits perfectly into this view.

The second approach to the six-stroke engine uses a second opposed piston in each cylinder that moves at half the cyclical rate of the main piston, thus giving six piston movements per cycle. According to its mechanical design, the six-stroke engine with external and internal combustion and double flow is similar to the actual internal reciprocating combustion engine. However, it differentiates itself entirely, due to its thermodynamic cycle and a modified cylinder head with two supplementary chambers: a combustion and an air heating chamber, both independent from the cylinder.

Combustion, does not occur within the cylinder but in the supplementary combustion chamber, does not act immediately on the piston, and it's duration is independent from the degrees of crankshaft rotation that occurs during the expansion of the combustion gases work.

Valve 1 is open.

Valve 2 is open. During 3rd and 4th stroke the temperature of the pure compressed air in the heating chamber is raised sharply by heat exchange from combustion chamber.
