Cars Opel Corsa B, Tigra and Combo – the summary
Model Opel Corsa B has been presented to Great Britain in March, 1993 on replacement previous Corsa, models «A». Model Tigra has been let out in November, 1994. The specified models belong to a class of small-displacement and economic cars and have рядные 3 or 4-cylinder engines with water cooling. The power unit is located in an impellent compartment across a direction of movement of the car and inclined forward.
The block of cylinders of the engine is executed from grey pig-iron. In the bottom part of the block of cylinders the cranked shaft leaning against radical bearings is located. Through шатунные bearings and rods the cranked shaft incorporates to pistons. From below the engine is closed by the pallet картера in which in the course of work the oil intended for greasing and cooling of moving parts of the engine gathers. The head of cylinders is executed from an easy alloy and fastens to the block of cylinders bolts. In a head of cylinders запрессованы saddles and the directing plugs of valves executed from a steel. Aluminium application improves a heat-conducting path and reduces weight of the engine.
The head of cylinders is executed under the so-called cross-section scheme of a purge. It means that the fresh air-fuel mix arrives on the one hand heads of cylinders, and the fulfilled gases leave on the other hand.
Petrol engines of 1.0 and 1.2 l3 or 4-cylinder engines of type DOHC have on 4 valves on the cylinder. Valves are set in motion by two camshafts through коромысла. For indemnification клапанных backlashes hydraulic pushers are established. Camshafts are set in motion by a chain.
The block of cylinders consists of two parts connected among themselves by bolts. The top part is executed from grey pig-iron, bottom – from aluminium. The bottom part is base for installation of radical bearings of a cranked shaft.
Petrol engines OHC of 1.2 and 1.4 lWith the top arrangement of a camshaft. The camshaft through коромысло actuates vertically located eight inlet and final valves. Hydraulic jacks automatically compensate formed клапанные backlashes. Thus, adjustment клапанного a backlash within the limits of maintenance service carrying out is not required. The Camshaft is resulted from a cranked shaft through a gear belt.
Petrol engines DOHC of 1.4 and 1.6 lWith two top camshafts actuating accordingly on two inlet and two final valves of each cylinder. Both camshafts are set in motion by a gear belt. The drive of valves is carried out by hydraulic pushers. Adjustment клапанного a backlash in the course of maintenance service carrying out is not required. The Mnogoklapannaja scheme provides good filling of cylinders and an effective conclusion of the fulfilled gases that in turn provides a fuel effective utilisation.
The diesel engine
Vertically located inlet and final valves are set in motion directly from a camshaft through тарельчатые pushers. Within the limits of maintenance service carrying out adjustment клапанных backlashes is required. The camshaft drive is carried out from a cranked shaft by a gear belt.
For engine greasing the oil pump fixed in front in the bottom part of the block of cylinders is used. On petrol engines the oil pump is set in motion directly from a cranked shaft, and on diesel engines - a gear belt. Oil from the pallet картера arrives through apertures and channels to bearings of cranked and distributive shaft, and also on walls of cylinders.
The pump of a cooling liquid (the water pump) on 4-cylinder petrol engines is in front in the block of cylinders and is set in motion by a gear belt. On petrol engines DOHC of 1.0 and 1.2 l the water pump is in front on case GRM and is set in motion
For preparation of an air-fuel mix on petrol engines the system of the central or distributed injection serves. Diesel engines are equipped by different high profitability system of direct injection of fuel with electronic control ТНВД set in motion by a gear belt.
On petrol engines the spark for ignition of an air-fuel mix is generated by electronic system of ignition. Adjustment of the moment of ignition within the limits of maintenance service is not required.
Engines meet the modern requirements under the maintenance the fulfilled gases of toxic components.
Transfer of a twisting moment from the engine to shaft of a drive of forward wheels is carried out by means of a 5-step manual box of a gear change established on the left side of the power unit (РКПП), or 4-step automatic transmission (АТ), - Heads Manual 5-step box of a gear change and Automatic 4-step transmission more in detail seeManual 5-step box of a gear changeAutomatic 4-step transmission.
The brake system is equipped by the regular vacuum amplifier. On all models disk brake mechanisms of forward wheels and back drum-type brake mechanisms are used. The standard complete set of the majority of models includes system ABS.
Completely the independent suspension bracket of forward wheels consists of racks of MakFersona and cross-section bottom levers. The suspension bracket of back wheels - semiindependent with торсионной a beam and two longitudinal levers, - see the Head the Suspension bracket and a steering more in detail.
Steering - реечное, with the hydraulic booster, the steering mechanism is located behind the engine. The electrohydraulic steering pump is established directly on the steering mechanism and does not demand service. The tank of a hydraulic liquid is built in pump assemblage, - the Suspension bracket and a steering see the Head.
Both series (Corsa B and Tigra) are equipped with the full-size driver's pillows of safety established as the standard equipment. Lateral pillows of safety can enter into an additional complete set. The system is applied to protection against breaking иммобилизации the engine. The regular radio tape recorder is equipped by a protective code.
