Four-cylinder enginesThis Part of Head is devoted not connected with extraction from the car (in situ) to repair of the 4-cylinder petrol engine in volume of 2.3 l, the injection of fuel equipped with system. All procedures demanding dismantle of the power unit, are given in the Part the General and major maintenance of the engine of the present Chapter.
Two versions of engines of 2.3 l are applied to a complete set of the considered Honda Accord models. The engine of the F23А5 series represents the base version whereas the F23А1 and F23А4 series represent actually the same design equipped with one of two variations of the device of correction of phases of a gazoraspredeleniye (VTEC) (see. Section Removal, check of a condition and installation of assembly of yokes).
Descriptions of the most part of considered procedures are made on the basis of the assumption that the power unit remains on the regular place in an impellent compartment of the car. In view of told in case the engine is already dismantled and established on a workbench or the assembly stand, many of described steps should be lowered.
All considered 4-cylinder engines are equipped with one camshaft having the top arrangement (SOHC) and operating functioning of 16 valves (on 4 on each of cylinders). The engine has the compact design which main component are the block made of an easy aluminum alloy and a head of cylinders. Two balancing shaft which main appointment is decrease in level of the vibrations resulting jet forces, enclosed to pistons and a cranked shaft enter into a design of the unit.
The cranked shaft is planted in the radical bearings which covers are drawn to the block by means of the general bridge. The fourth radical bearing is persistent and in addition supervises axial люфт in bulk.
Pistons are equipped by two kompressionny and one maslosjemny rings. Piston fingers having semi-floating landing are pressed in the top heads of rods. In the bottom heads replaceable loose leaves of shatunny bearings are located.
The engine has liquid cooling on the basis of the centrifugal rotor pump put in action from a gear belt. Cooling liquid circulates on internal galleries of the engine, washing cylinders and combustion chambers, and also is banished on the channels equipped in the inlet pipeline.
Supply of greasing to internal components of the engine is carried out by the shesterenchaty oil pump located in a forward part of the engine under a cover of a gas-distributing belt. The drive of an internal gear wheel of the pump is carried out directly from a cranked shaft. Oil is sucked in via the mesh filter of type from the case pallet, then banished via the polnopotochny filter of the cartridge type established on turned to a back partition of an impellent compartment to the party of the power unit.
