Title: Internal combustion engine

Abstract

An internal combustion engine is described comprising: (a) an engine body having a chamber; (b) a crankshaft rotatably mounted on the engine body; (c) a camshaft rotatably mounted on the engine body; (d) an oil lubricated endless transmission member extended around and operatively engaged with the crankshaft and the camshaft, the endless transmission member being movable along a closed path of travel in the chamber; (e) a tensioner hanger comprising an upper hanger member detachably secured to the engine body and a lower hanger member secured at an upper portion thereof to the upper hanger member, the upper hanger member having oil passage means adapted to receive lubrication oil from the endless transmission member at an inlet and guide the oil downwardly therethrough to an outlet; (f) a hollow mounting member affixed at an upper portion thereof to a lower portion of the lower hanger member of the tensioner hanger; (g) a hydraulic lock mechanism comprising a hollow cylinder and a plunger slidably received in the cylinder to define a hydraulic chamber in the cylinder; (h) a replenishable oil reservoir defined by a funnel-shaped space between the mounting member and the cylinder for receiving oil from the oil passage meansmore » and for holding the oil received therein; and (i) a tensioner member movably attached to the engine body and operatively engaged with the plunger.« less

  • An apparatus is provided for introducing secondary air into an internal combustion engine. The apparatus has an air pump coupled to an air injection pipe system, the latter having an end terminating upstream of the catalytic converter, for introducing an amount of secondary air into the exhaust system of the engine. The apparatus further includes a valve device for maintaining the secondary air directed to the exhaust system from the air pump at determined constant pressure; thus, the amount of secondary air introduced into the exhaust system is effectively decreased during high rotational speed engine operation in order to preventmore » the catalytic converter from being overheated.« less
  • A method of operating an internal combustion engine with a split chamber design for stage combustion comprising the steps of: forming at least one primary combustion chamber and at least one secondary combustion chamber in association with a cylinder means having at least two regions formed therein and piston means within the engine, causing air within the cylinder means to flow through the at least one primary combustion chamber at a predetermined rate and volume; admitting a predetermined amount of fuel to the at least one primary combustion chamber to form a fuel/air mixture, therein; igniting the fuel/air mixture withinmore » the at least one primary combustion chamber to generate a first stage of combustion; causing the flow of the the ignited fuel/air mixture to the at least one secondary combustion chamber for continued burning of the fuel/air mixture in a second stage of combustion within the at least one secondary combustion chamber. This patent also describes a split chamber, staged combustion internal combustion engine. It comprises means defining a cylinder having at least two regions formed therein, piston means; combustion chambers; fuel delivery means; and means for igniting the fuel in the primary combustion chamber.« less
  • A method is described for operating an internal combustion engine with a gasoline combustion charge, which comprises introducing with the combustion charge into the engine an octane requirement increase-inhibiting amount of (a) gasoline-soluble iron compound and (b) a gasoline-soluble oxygen-containing compound selected from the group consisting of carboxylic acids and ester derivatives thereof. The engine has a combustion surface characterized as having a combination of thermal conductance and thermal penetration properties which inhibit the build-up of deposits resulting from combustion in the engine, without substantially raising the temperature of the incoming combustion charge.
  • An internal combustion engine is described comprising a cylinder body having a pair of adjoining first and second cylinders, a reciprocable piston in each cylinder, first valve means for introducing a fuel mixture in the first cylinder, second valve means for discharge of exhaust gases from the second cylinder, a combustion chamber mounted adjacent the cylinder body for movement between the cylinders and communicating in one position with the first cylinder and in a second position with the second cylinder, the combustion chamber receiving compressed fuel mixture from the first cylinder in the one position, and means for igniting themore » compressed fuel mixture in the combustion chamber as the chamber moves from the first to the second position, the combustion chamber delivering combusted fuel mixture to the second cylinder in the second position.« less
  • The apparatus is particularly provided for an overhead cam type engine in which cam lobes directly act upon the upper side of rocker arms. A hydraulic piston is formed under a floating stud pivotally supporting the rocker arm thereon for cooperation therewith and is hydraulically operated through a solenoid-operated directional control valve between a normally operating position and a locking position in which an engine valve is deactivated. The control valve is actuated from an electronic system to render one or more cylinders inactive for certain engine power output.
