Renault H4B 0.9 TCE Engine Specs, Problems, Reliability. The small 0.9-liter turbocharged three-cylinder engine H4Bt was developed collectively with Nissan Company (Renault named all these engines as H series and Nissan – HR series). The engine combined all modern-day innovation for today available in the affordable market sector. Renault pursued the strategy of scaling down in the engine development and using turbocharging for increasing engine effectiveness.
The cylinder block made from light aluminum alloy for reducing the weight. The cylinder head is likewise aluminum. It has 2 overhead camshafts and four valves per cylinder (12 valves overall). The consumption camshaft geared up with variable valve timing system VVT.
The repaired geometry turbocharger is integrated into the exhaust manifold and integrated with VVT system guarantees that optimum torque is offered at low engine speeds and across a broad rev-band (increase pressure 2.05 bar). 0.9 l TCE engine has lifetime timing chain, variable displacement oil pump, spark plugs with specific coils. The electronic multipoint injection system (indirect injection) provides fuel into cylinders.
The engine is effective and quite torquey for little A and B class cars. The brand-new choices in style permitted lowering fuel intake by 25, and at the same time, the engine satisfies Euro5 and Euro6 European emission standards (environment-friendly motor). The engine service intervals were decreased which also lowering the expense of maintenance.
