Lada Car Engine
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 enginesandgearboxes.co.uk 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
As another advantage, the shape of the Wankel combustion chamber and the turbulence
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.
The Lada Samara
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 Signet, Riva 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.
