Lada Car Engine

Published by Carl Wilson on

Lada Car Engine: Samara engine, Kalina, 1500 and more Lada models was produced in various three, four and five door designs with engine displacements 1.1, 1.3 and 1.5 litre petrol car engines. Their engine is a Wankel rotary engine and is a type of internal combustion, invented by German engineer Felix Wankel and are available at as used, reconditioned or secondhand. Lada car engines use a rotor instead of reciprocating pistons. This design delivers smooth high-rpm power from a compact, lightweight engine.

Wankel engines have several major advantages over reciprocating piston designs, in addition to having higher output for similar displacement and physical size. Wankel engines are considerably simpler and contain far fewer moving parts. For instance, because valving is accomplished by simple ports cut into the walls of the rotor housing, they have no valves or complex valve trains; in addition, since the rotor is geared directly to the output shaft, there is no need for connecting rods, a conventional crankshaft, crankshaft balance weights, etc. The elimination of these parts not only makes a Wankel engine much lighter (typically half that of a conventional engine with equivalent power), but it also completely eliminates the reciprocating mass of a piston engine with its internal strain and inherent vibration due to repetitious acceleration and deceleration, producing not only a smoother flow of power but also the ability to produce more power by running at higher rpm. The simplicity of design and smaller size of the Wankel engine also allows for savings in construction costs, compared to piston engines of comparable power output.
As another advantage, the shape of the Wankel combustion chamber and the turbulence induced by the moving rotor prevent localized hot spots from forming, thereby allowing the use of fuel of very low octane number without preignition or detonation, a particular advantage for Hydrogen cars.

In addition to the enhanced reliability due to the elimination of this reciprocating strain on internal parts, the engine is constructed with an iron rotor within a housing made of aluminum, which has greater thermal expansion. This ensures that even a severely overheated Wankel engine cannot seize, as would likely occur in an overheated piston engine.

Felix Wankel managed to overcome most of the problems that made previous rotary Otto cycle engines fail by developing a configuration with vane seals that could be made of more durable materials than piston ring metal that led to the failure of previous rotary designs.

Rotary engines have a thermodynamic problem not found in reciprocating engines in that their “cylinder block” operates at steady state, with intake, compression, combustion, and exhaust occurring at fixed housing locations for all “cylinders”. In contrast reciprocating engines performs these four strokes in one chamber so that extremes of freezing intake and flaming exhaust are averaged and shielded by a boundary layer from overheating working parts. Freezing temperature from evaporating fuel prevail at the intake while ignition reaches temperatures of about 2300 Kelvin that are higher than lubricants and most engine materials can withstand.
This thermodynamic effect has dissuaded most engine manufacturers from further pursuing a reliable rotary engine, some having spent enormous sums on development to make the Wankel mechanically competitive with reciprocating engines.

The Lada Kalina. There are two gasoline engines, with 80 and 91 hp (60 and 68 kW).

The Lada Riva. It was marketed as the Lada Nova in some (not all) European countries, as the and as the Lada 1500 and Lada Signet in Canada. Model variants included the Riva SignetRiva 1200, Riva 1300, Riva 1500, and Riva 1600, with trim levels “E” and “L”. On the original Russian market the only model is 1500. Engine sizes were 1.2, 1.3, 1.5, 1.6 petrol and 1.7 diesel.

Their internal combustion engine is an engine in which the burning of a fuel occurs in a confined space called a combustion chamber. This exothermic reaction of a fuel with an oxidizer creates gases of high temperature and pressure, which are permitted to expand. The defining feature of an internal combustion engine is that useful work is performed by the expanding hot gases acting directly to cause movement, for example by acting on pistons, rotors, or even by pressing on and moving the entire engine itself. This contrasts with external combustion engines, such as steam engines and Stirling engines, which use the combustion process to heat a separate working fluid, which then in turn does work, for example by moving a piston.
