The 1.4-liter 16v FIRE engine (for “Fully Integrated Robotised Engine”) which will be used on the up coming Tata Indigo has a sprinkling of exciting technology. Therefore, I felt it would be an excellent idea to put forward the facets of the engine in this article for you to relish. I have also explained each point from an engineering perspective.
Technical Specification of Fiat 1.4 engine
1368 cc
4-cylinders, 16 valves
Power: 95 bhp @ 6000 rpm
Torque: 97 lb.ft @ 4250 rpm
Highlights of the Fiat 1.4 engine
With a bore of 72 mm and stroke of 84 mm, the 1.4 16v FIRE unit is coupled to a drive-by-wire, electronic throttle control system.
The 1.4 16v FIRE has a high compression ratio and delivers more torque at low revs, which help in decreasing fuel consumption
An engine’s volumetric efficiency decides how much power you can possibly extract from it. Fiat’s engineers used Fluid Dynamics study to get maximum volumetric efficiency from the available 1,368 cc.
Fiat uses lighter timing components and low-load type valve springs on the 1.4 16v FIRE .
Fuel adhering to the inlet manifold walls during winter mornings is averted on the 1.4 16v FIRE by a new injector which optimizes fuel spray phase.
1.4 16v FIRE shares Fiat’s 1.2 litre engine’s barycentric engine mounting system to reduce the transfer of vibrations to the body
An aluminium crankcase base with cast iron main bearing caps cast together, an aluminium oil sump connected directly to the base of the crankcase and gearbox to increase the torsional rigidity of the combined unit.
A crankcase and flywheel system damper to minimise vibration; and an optimized piston skirt profile with a molybdenum bisulphate coating to minimise piston/liner clearances and thus reduce noise.
1.4 16v FIRE is fully Euro 4 compliant.
