Abstract

The utility model relates to an in-line piston engine utilizing waste gas energy, in particular to the engine which utilizes recoil force generated when waste gas exhausts and is suitable for military use and civil use. The in-line piston engine utilizing the waste gas energy is composed of a Laval-type spraying pipe, an exhaust valve assembly, a spark plug (or an oil spraying nozzle), an intake valve, a gas inlet channel, a cylinder cover, a cylinder body, a piston and a connecting rod. The in-line piston engine utilizing the waste gas energy has the advantages that the cylinder is horizontally placed, the exhaust valve is arranged backwards, the engine is driven by the recoil force generated when the waste gas is ejected backwards from the cylinder through the exhaust valve to move forwards, and thrust is acquired and efficiency is improved on the basis that the exhaust back pressure of the engine is not increased and the power of the engine does not lose; the in-line piston engine utilizing the waste gas energy is compatible with the prior in-line piston engine, can be acquired through improvement of a cylinder cover, an oil pan, a fixing support, an intake valve, an exhaust valve, a gas inlet channel and an exhaust channel of the prior in-line piston engine, and is low in improvement cost.

Description

A kind of type reciprocating engine in upright arrangement that utilizes exhaust energy

Technical field

The utility model relates to a kind of type reciprocating engine in upright arrangement that utilizes exhaust energy, specifically refer to a kind of when type reciprocating engine waste gas in upright arrangement is discharged in the cylinder, the motor that utilizes of the recoil force that produces, especially a kind of type reciprocating engine in upright arrangement that is applicable to that military and civilian are dual-purpose.

Background technique

On existing automobile, naval vessel, motor on the aircraft that propeller cavitation advances, the two-stroke of employing or four-stroke are arranged more, the reciprocating engine of type single cylinder in upright arrangement or multi-cylinder, utilize fuel to burn in cylinder combustion and produce high-temperature high-pressure fuel gas, promote piston, obtain rotation by connecting rod, bent axle again and promote locomotive.As the motor that uses on the present automobile, have only 30% energy to be converted into mechanical energy in the energy that petrol engine combustion produces at most, diesel engine also has only 40% energy to be converted into mechanical energy, in the energy that oil inflame produces, also having greatly, energy is lost among the atmosphere by toxic emission.

This class motor is after expansion stroke finishes, waste gas is discharged through valve from cylinder, enter in the gas exhaust manifold, radiating and cooling, after volume increased, pressure had 3～5 barometric pressure, and temperature reaches 600 ℃～700 ℃, as seen still contain more energy, this energy is exactly the energy source that existing exhaust gas turbocharge utilizes.And the contained energy of these waste gas also has the temperature height, and pressure is big, and the characteristics that flow velocity is fast can instead push away thus, and the energy amount temperature that waste gas has when discharging in cylinder is higher, and pressure is bigger, and flow velocity is faster.

The waste gas of existing type reciprocating engine in upright arrangement all sprays obliquely, the recoil force that produces during ejection, then be under oblique, this recoil force not only fails to be used to promote locomotive, has become to cause the strength of the vibration (during the slow-speed of revolution) of motor or twisting when rotating speed (high) on the contrary.

Summary of the invention

The one, obtain recoil force when utilizing waste gas to discharge in the cylinder and directly promote locomotive.

The 2nd, when type reciprocating engine waste gas in upright arrangement was discharged, the engine luggine that causes and the recoil force of twisting became the thrust that locomotive advances, thereby reduce the vibration of whole locomotive.

The 3rd, motor becomes horizontal positioned, has reduced the center of gravity of locomotive, improves the stability of travelling of locomotive.

Implementer's case is as follows

A kind of type reciprocating engine in upright arrangement that utilizes exhaust energy of the utility model design, by Laval nozzle (1), exhaust valve control assembly (2), spark plug (or oil nozzle) (3), intake valve (4), intake duct (5), cylinder head (6), cylinder block (7), piston (8), connecting rod (9) is formed, and described piston (8) is arranged in the cylinder block (7), cylinder block (7) is connected with cylinder head (6), and cylinder head (6) is connected with Laval nozzle (1).

Described cylinder head is provided with exhaust valve, intake valve, and spark plug (or oil nozzle), wherein exhaust valve is placed in the middle, intake valve and spark plug (or oil nozzle) separation both sides.

Described exhaust valve control assembly is arranged in the Laval nozzle, and exhaust valve control assembly is airtight by shell, and shell is connected and fixed with the Laval nozzle inwall, and places in the Laval nozzle middle.

A kind of type reciprocating engine in upright arrangement of exhaust energy that utilizes of the utility model has following beneficial effect:

The one, with the cylinder horizontal positioned, exhaust valve backward, utilize waste gas in the cylinder when exhaust valve sprays backward, as the recoil force of balloon, the recoil that produces during the firearms emission is the same, produce recoil force, promote locomotive and travel forward, obtain a high-grade motive force that does not need middle transmission link, do not increasing the engine exhaust back pressure, do not lose under the prerequisite of engine power, obtain thrust, raise the efficiency.

The 2nd, can be effectively compatible existing type reciprocating engine in upright arrangement only need improve get final product the cylinder cap of motor, oil sump, fixed bearing, intake and exhaust gateway etc., and the improvement cost is low.

Embodiment

For the ease of those skilled in the art's understanding, below in conjunction with specific embodiment and accompanying drawing structural principle of the present utility model is described in further detail:

Internal-combustion engine is in expansion stroke, and wherein petrol engine combustion gas pressure can reach 3050 barometric pressure, and temperature reaches 2000-2500 ℃; The combustion gas pressure of diesel engine can reach 50-100 barometric pressure, and temperature reaches 1700-2000 ℃, and in the back to back exhaust stroke, the energy that the waste gas of discharge has shows as the temperature height in form, and pressure is big, and flow velocity is fast.When just spraying in the cylinder of waste gas from shown in the accompanying drawing 1, must produce a recoil force to piston, this recoil force can pass to bent axle through connecting rod, and bent axle is passed to the engine housing that supports it again, passes to locomotive again, advances thereby directly promote locomotive.

The principle that the generation of this recoil force and rocket produce recoil thrust is identical, according to the rocket thrust formula:

Thrust=propellant flow rate * jet velocity+(nozzle exit pressure-ambient pressure) * nozzle exit area

This recoil force that produces during the waste gas ejection forms equidirectional making a concerted effort with the thrust that obtains from tire, promotes locomotive jointly, and during as start, the someone draws or pushes away the same.And this recoil force, for promoting locomotive, be directly, there are not middle transmission link loss, high-grade motive force.

For type piston type multicylinder engine in upright arrangement, each cylinder wherein will produce a recoil force when exhaust stroke, promotes locomotive and advances.

Foregoing only is an embodiment of the present utility model, is not that those skilled in the art are according to design of the present utility model for restriction embodiment of the present utility model, and the appropriate adaptation of having done or modification all should be within protection domains of the present utility model.
