DE102005031946A1 - Modular design for range of in line and V-type IC engines with the inline engines fitted into the contours of one side of the V-engines - Google Patents

Abstract

A modular design for a range of engines, both inline and V-type, has the inline engines fitted into the contour of one side of the V-engines, and with similar connecting profiles for both ends of both types of engine. This ensures a cost effective fitting into a range of vehicles, with similar crankshaft supports, oil sump and accessories. The design can be applied to diesel engines as well as ignition fired engines, for both gas and fuel systems. The inline engines are mounted with a lateral tilt, to fit into part of the V-engine envelope.

Description

The The invention relates to an engine family with in-line engines and V-engines, wherein the In-line engines of a single cylinder bank with at least two adjacent cylinder units and the V-engines consist of two at an angle to each other arranged cylinder banks, each with at least Two adjacent cylinder units exist and each engine front and rear end of the crankcase as completion of the cylinder banks as well having lateral components.

at known engine families, consisting of a large number of cylinder types with V-arrangement or series arrangement, the problem occurs on that at the transition from series arrangement to V arrangement or vice versa the front and rear end of the crankcase as Completion of the cylinder banks can not be subjected to the modular principle.

In order to The number of identical parts desired for cost reasons is also very low and is usually limited to one cylinder unit.

Of the Invention is based on the object, an engine family after the The preamble of claim 1 in such a way that the in-line engines and the V-engines a big one Have number of identical parts.

According to the invention this Task solved by that the in-line engines are adapted to the V-engines and a cylinder bank identical to one of the two cylinder banks of the V-engines is and, in contrast to the V-engines, the second cylinder bank The V engines are so removed that the front and rear ends of the crankcase and the lateral components are identical in both engines. Thereby is created an engine family in which the inline engines and the V-engines a big one Have number of identical parts.

• a) Eine Zylinderbank bleibt vollständig unverändert.
• b) Die Lagerstellen einer zentralen Nockenwelle bleiben unverändert.
• c) Der Freigang für die Gegengewichte der Kurbelwelle bleibt erhalten.
• d) Die Kontur des Reihenmoors wird so gestaltet, dass die Dichtfläche des vorderen und hinteren Räderkastendeckels erhalten bleibt.
• e) Die Ölwannendichtfläche bleibt unverändert.

In a preferred embodiment, the dividing line at the transition from the V-engine to the in-line engine is such that at least some and preferably all of the following conditions are met:

• a) A cylinder bank remains completely unchanged.
• b) The bearings of a central camshaft remain unchanged.
• c) The clearance for the counterweights of the crankshaft is maintained.
• d) The contour of the row bog is designed so that the sealing surface of the front and rear timing case cover is maintained.
• e) The oil sump density remains unchanged.

The motors according to the invention are advantageous diesel engines with mechanical or electronic Injection or gasoline or gas engines.

One Inventive in-line engine with a single cylinder bank consisting of at least two adjacent ones Cylinder units exists and with a front and rear end of the crankcase as completion of the cylinder bank as well as with lateral components, is characterized in that the in-line engine known per se Adapted V-engines is and has a cylinder bank at an angle to a through the crankshaft going vertical plane is arranged.

Further advantageous embodiments of the invention are the drawing description can be seen in the illustrated in the figure embodiment closer to the invention is described.

The figure shows in section a V-engine 2 an engine family consisting of two cylinder banks arranged at an angle to each other 3 . 5 each with at least two adjacent cylinder units 4 consists. Not shown are the front and rear ends of the crankcase as completion of the cylinder banks 3 . 5 , Of the lateral components, for example, the intake pipes 10 and exhaust pipes 11 shown.

The in-line engine according to the invention 1 is adapted to the just described V-engine of the engine family. For better understanding is also the in-line engine 1 shown in the figure, as it emerges from the V-engine of the series.

This in-line engine 1 consists of a cylinder bank 3 with at least two cylinder units 4 , At the transition from the V-engine 2 to the in-line engine 1 becomes the second cylinder bank 5 the V engine so removed that the front and rear ends of the crankcase and the side components in both engines 1 . 2 are identical. The dividing line of the in-line engine 1 to the V-engine 2 is with the reference numeral 6 characterized.

The dividing line 6 at the transition from the V-engine 2 to the in-line engine 1 lies so that a cylinder bank 3 remains completely unchanged, that the bearings of a central camshaft 7 remain unchanged, that the clearance for the counterweights of the crankshaft 8th maintained that the contour of the in-line engine is designed so that the sealing surface of the front and rear timing case cover he keeps and that the oil pan sealing surface remains unchanged, so that identical oil pans can be installed.

The just described engines are self-igniting internal combustion engines, So diesel engines with mechanical or electronic injection.

This engine family according to the invention with in-line engines and V-engines has the following identical parts of the two engine series:
Counterweights of the crankshaft 8th , Crankshaft bearing, camshaft bearing, conrod and connecting rod bearings, cylinder tubes, pistons with piston rings, cylinder head complete, injection pump 12 as such, apart from the number of pump elements, injection lines, injectors, fuel delivery pump, control unit, exhaust pipes, pulse converters, turbocharger, intake manifold, front cross connection, oil sump, subframe, front wheel drive, water pump, oil pump, rear cover, rear wheel drive, SAE Housing, oil cooler, thermostat housing, crankcase breather, starter, fan bracket for belt fan.
