Abstract

The invention relates to an internal combustion engine comprising at least one cylinder that is horizontal or inclined below the horizontal plane, including a cylinder head (1) provided with lubrication means, and a distribution system. The cylinder head (1) comprises an oil return pump drawing the oil into the low point of the cylinder-head cover (18) and discharging the oil towards the main crankcase of the engine.

Description

Including at least one level or the oil suction of internal combustion engine of the cylinder at horizontal plane inclined downward System
Technical field
The present invention relates to field of internal combustion engine, more particularly, it relates to have level or the gas at horizontal plane inclined downward The electromotor of cylinder.The framework (such as, cylinder is not placed side by side the automobile of structure or places side by side the motorcycle of amphistyly) of vehicle Or the purposes of vehicle (such as, aircraft (the most aerobatic aircraft) or rubbing of being fixed on parking bracket Motorcycle) such situation can be caused.
Background technology
Cylinder head is typically the removable top of reciprocating-piston engine.The top of cylinder head closed cylinder.At some In electromotor, intake valve and air bleeding valve are contained in cylinder head.The shape of cylinder head and characteristic often design with electromotor The progress of aspect is closely related, and more specifically, and the shape of cylinder head and characteristic are according to the timing type of combustor And the shape of combustor determines.
German patent application DE4424248 known in the art, The patent application describes one and has for air-discharging The gear pump of cylinder cap place side by side six cylinder h type engine hs.
Such as apply for DE102008014828, DE2020100123697, JP S60192820, JP H08100614 Or other patent applications of DE4007939 etc describe the multiple solution for air-discharging cylinder cap.
The defect of prior art
Problem of the prior art is, when, during cylinder head is in obliquity or when being horizontal middle, oil is detained In the lower position of cylinder head.Due to the high temperature of cylinder head, the horizontal plane of oil is raised in cylinder head, causes oil splashing And it is impregnated with valve, thus produces cigarette.
Specifically, for having at the electromotor of horizontal plane inclined downward and the cylinder of longitudinal extension, due to Out of season oil transmission is occurred to cause particular problem during brake suddenly or strength are accelerated.
Summary of the invention
In order to remedy these defects, according to approve most, the present invention provides a kind of internal combustion engine, and this internal combustion engine has at water At least one cylinder of plane inclined downward and there is cylinder head and the timing system being provided with lubricating structure, described Internal combustion engine is characterised by, described cylinder head has scavenge oil pump, and this scavenge oil pump is from the bottom of cylinder head lid suction oil also And oil is delivered to the main shell of described electromotor.
Advantageously, described pump is driven by described timing system.
Preferably, in described cylinder head, machine the pump housing and closed the described pump housing by lid.
In a specific embodiment, the described pump housing opens in suction socket.
Advantageously, described pump is trochoid pump.
Detailed description of the invention
Read the non-limiting embodiment that is given referring to the drawings described below on the basis of will be better appreciated by this Invention, in the accompanying drawings:
Fig. 1 is 3/4ths front views of the cylinder head opened of electromotor;
Fig. 2 is 3/4ths front views of the cylinder head of electromotor, the figure shows without cylinder head lid or pump The rotor of the pump of lid;
Fig. 3 is without cylinder head lid and 3/4ths front views of the cylinder head with pump cover body;And
Fig. 4 shows the rearview of the cylinder head shown in Fig. 3.
Present invention is preferably related to the bi-block engine with opposed cylinder, cylinder is relative to vehicle (especially motorcycle) It is longitudinally arranged.Cylinder is inclined relative to horizontal about 25 degree of angles.One of them cylinder is downward-sloping, another cylinder It is inclined upwardly.
Lubricating oil tends to accumulate in the cylinder head of bottom, it should remove it.For vertical cylinder, by Gravity oil-removing.For the electromotor of level or inclination, by gravity or utilize pump oil removing.At brake process In when oil returns by gravity, the oil from oil trap or engine housing can be via removing pipe towards cylinder head liter Height, this is undesirable.
Fig. 1 shows the view of cylinder head 1 and cylinder 2.Cylinder head 1 is shown to upper half axle without cylinder head Hold or pump.
Cylinder head has exhaust camshaft 3 and inlet camshaft 4.
At cylinder head end, cylinder head 1 has extension 5, and the half-and-half bearing 6 shown in Fig. 2 is executed against extension 5 Add.
The first semi cylindrical portion 8 of the pump housing 7, and machine in half-and-half bearing 6 is formed by machining in extension 5 It is processed into the second semi cylindrical portion 9 of the pump housing 7.
Internal rotor 10 and outer rotor 11 are contained in the pump housing 7.Internal rotor 10 supported by camshaft mandrel end 12 and by Pin 13 drives.
Lid 14 canned pump.The inner surface of lid 14 has entrance recess 15 and discharges recess 16.By aperture 17 Suction oil, aperture 17 will be located in the discharge area 18 of the foot of cylinder head and is connected to the entrance recess 15 with lid Logical cylinder head enters recess 19, for oil pump feed.
Oil is sucked between internal rotor 10 and outer rotor 11, and is delivered to recess 16.Described recess 16 with Recess 20 UNICOM so that then oil is discharged into along a series of holes that axis 21 extends, enters into the master of electromotor In shell.
