Abstract
This invention relates to an internal combustion engine for a motorcycle, with two or more single cylinders arranged in a plane approximately normal to a crankshaft, each cylinder accommodating a reciprocating piston and the pistons acting via connecting rods on the same crank of the crankshaft supported in a crankcase. To reduce manufacturing expense, the engine is to be provided with modular components for universal use with at least two different cylinder arrangements (V-type, W-type).
Description
Technical field
The present invention relates to a kind of motorcycle IC engine, it has two or more single-cylinders that are installed on the plane that is approximately perpendicular to bent axle, a reciprocating piston is installed in each cylinder, and each piston utilizes some connecting rod work, and these connecting rods are on the same crank that is installed in the bent axle in the crankcase.
Background technique
294 264 li of U.S. Pat D, the motorcycle IC engine that is disclosed comprises two cylinders, and this two cylinder is arranged to V-type and radially faces toward a bent axle, and each cylinder acts on the crank by connecting rod.The characteristics of this type internal-combustion engine are very compact and have very short overall length, therefore it laterally can be installed on the motorcycle.Because layout and space, the cubic capacity of each cylinder is limited.Total cubic capacity can only improve by increasing more cylinder, yet this is with the overall length of increasing combustion engine.
Disclosed in the prior art another alternative embodiment is used three cylinders, and they are installed into radially the bent axle of internal-combustion engine relatively, wherein, by each connecting rod on the common crank of the piston action that slides in the cylinder at bent axle.This cylinder becomes internal-combustion engine that the W type arranges at U. S. Patent the 5th, 765, introduction is arranged in No. 451.Have W type cylinder structure and these cylinders be located substantially on the compact structure that also can obtain to have very short overall length perpendicular to the internal-combustion engine in the plane of bent axle.Compare with V-type internal combustion engine, extra cylinder will improve the performance characteristic of internal-combustion engine and significantly increase its cubic capacity, and keep smaller volume simultaneously.And big piston sweep volume will allow to have good engine performance when relatively low rotating speed, and have internal-combustion engine sound typical, fully loaded, relative low frequency.
V-type and the different performance of W type internal-combustion engine will satisfy different Consumers' needs.
In order to satisfy on the one hand the requirement of V-type internal combustion engine, to satisfy the requirement of W type internal-combustion engine on the other hand, in normal circumstances different manufacturing and delivery system must be installed, and this will need considerable manufacturing and logistic work, comprise high manufacturing expense.
Summary of the invention
An object of the present invention is to avoid above-mentioned defective, so that reduce the expense of the internal-combustion engine of making the above-mentioned type.
In the present invention, this purpose is by using the modular type spare part in common use that is applicable to two kinds of different cylinder structures at least to realize.A kind of modular system that supplies motorcycle IC engine to use, this internal-combustion engine has at least two and is arranged in perpendicular to the single-cylinder on the plane of a bent axle, one reciprocating piston is installed in each cylinder, piston acts on by connecting rod on the same crank of the bent axle that is positioned in the crankcase, wherein, described system is provided with general modular parts in V-type cylinder structure and W type cylinder structure, and the described crankcase that is used for described V-type cylinder structure or described W type cylinder structure has identical crankcase body and the different flange surface of using for the cylinder of described V-type cylinder structure or W type cylinder structure.
By provide at least one group with cylinder arrangement become the corresponding internal-combustion engine of V-type identical, by the part that cylinder head, cylinder, piston, connecting rod, series of valves are formed, can improve internal-combustion engine operation simplification and the effect ratio of forming by at least three cylinders that become the W type to arrange during fabrication satisfactorily.
In addition, preferably also provide at least one group to become the corresponding internal-combustion engine of V-type part identical, that form by trunnion shaft, equilibrium block, starter, generator, clutch, torque limiter, manual drive, oil pump, water pump with cylinder arrangement.If the part of same type can be used for V-type and W type internal-combustion engine,, therefore can simplify manufacturing process significantly on same production line because these parts can be made and assemble.Because modular design and part are shared principle, thereby can produce in enormous quantities, and then reduce production costs.If have at least one group to become the internal-combustion engine of V-type part identical, that, intermediate gear lubricated by food tray, oil cooler, dry type fuel feeding, belt and chain are formed, will further improve the effect ratio with cylinder arrangement.According to the type of internal-combustion engine, vaporizer or be used for multi-point injection or the injection apparatus of direct injection can be identical on type.
In order to reduce the manufacture cost of crankcase, suggestion is used the technological equipment identical with the crankcase body of the corresponding internal-combustion engine with V-type cylinder structure to the crankcase body of using for W type internal-combustion engine.Except the cylinder flange, can on identical production line, process with the crankcase that W type internal-combustion engine is used for V-type.
Large batch of shared part also has extra advantage, though available throughput be fully used, and make reduce to dead time minimum.
V-type internal combustion engine has the exhaust flange face usually, and they are positioned at the outer side surface of cylinder head.In order in V-type internal combustion engine and W type internal-combustion engine, to use identical cylinder and cylinder head, advise that each cylinder head has a front side exhaust flange face, this front side exhaust flange face preferably is positioned in the plane perpendicular to crankshaft center line.Like this, exhaust duct can be away from the front side of internal-combustion engine, thereby forms the enclosed space of cylinder, and makes the needed space of internal-combustion engine reduce to minimum.
In order in various type of internal combustion engine, to use one and same crankcase, this crankcase also to have for connecting the intermediate gear flange surface that intermediate gear is used.Intermediate gear as reduction gear can be designed to movably, so that can change reduction speed ratio.
Intermediate gear as reduction gear can also be provided, and it is removable, so that can change reduction speed ratio, also can obtain a special advantage by provide one to crankcase in its downside oil pan flange, promptly carries a food tray.Fuel tank or oil cooler form the lubricated part of dry type fuel feeding of internal-combustion engine.
