RU70691U1 - INTERNAL COMBUSTION ENGINE WITH REVERSE MOVEMENT OF CRANK-CONNECTING MECHANISM - Google Patents

Abstract

The utility model relates to the field of automotive engineering, river and navy, being an internal combustion engine (ICE) with a reciprocating movement of the crank mechanism. The design of the internal combustion engine provides for one camshaft. The number of cams rigidly mounted on the camshaft is half as much in this design as in the design with two camshafts, and this when the engine is working leads to a decrease in the coefficient of friction. Reducing the coefficient of friction will reduce the consumption of the amount of fuel consumed

Description

The utility model relates to the field of automotive engineering, river and navy.

The closest analogue of the claimed utility model is an internal combustion engine (ICE) with a reciprocating movement of the crank mechanism (application RU No. 2004127973 A, class F02B 75/32, publ. 2006.03.10)

The disadvantage of this analogue of the prototype is that it has two camshafts, which entails an increase in the coefficient of friction.

The technical task of the claimed utility model is the development and creation of internal combustion engines with a reciprocating movement of the crank mechanism with less fuel consumption.

As a result of solving the claimed technical problem, it is possible to obtain a technical result, which consists in reducing the coefficient of friction of rolling bearings located in each crank, in each connecting rod and on the camshaft.

The problem with the achievement of these technical results is solved by the fact that in an internal combustion engine with a reciprocating movement of the crank mechanism contains only one camshaft.

In addition, the rolling bearing cages are in place and rigidly fixed to the engine crankcase, and the rollers rotate in the direction in which the connecting rods and cranks rotate.

The implementation of the proposed utility model will increase the life of the engine and reduce fuel consumption.

In Fig.2 shows the internal combustion engine (side view);

Figure 3 shows the rolling bearing.

ICE consists of rolling bearings 1, engine crankcase 2 cylinders, crankshaft 3, camshaft 4, flywheel 5, trailer 6, cams 7, rocker arm 8, rods 9.

ICE works as follows: pistons moving press on the connecting rods, which in turn have an effect on the cranks. Rotating cranks drive the crankshaft. The flywheel is located on the same shaft with the trailer and removes the cranks from the dead points. The crankshaft is divided into parts, two connecting rods and one crank, and rolling bearings are installed between these parts. A camshaft connects two cranks to each other, and a trailer connects two opposite cranks. The cams, rigidly mounted on the camshaft, rotating with it, press on the rods and rocker arms, and the rocker arm pressing on the valves of the gas distribution mechanism. Cams with one camshaft are two times less than with two camshafts. Therefore, the coefficient of friction should be half as much with regards to the camshafts. The total engine is 1.5 times.

The engine will consume less fuel by using rolling bearings instead of liners. In this case, the lubrication system is greatly simplified.

The use of this design of the internal combustion engine allows to increase the service life of this engine and reduce fuel consumption by reducing the friction coefficient.
