Renault introduces 3 Energy engines, fuel economy up to 67mpg
The three new engines are the TCe 115 di, the Energy dCi 130, and the Energy dCi 110 (pictured). The TCE is a gasoline direct-injection engine while the other two are clean diesel technologies, the 110 capable of 3.5 liters/100km, which is equivalent to 67mpg U.S. Each engine has distinct new efficiency technologies to improve performance and reduce emissions.
The Energy TCe 115 is a 1.2-liter gasoline engine and is the first in Renault's line to feature direct fuel injection and turbocharging for fuel-efficient performance. Combined with its double cam-phasing Variable Valve Timing (VVT), it allows maximum torque at low engine speeds. This translates to much more efficient operation at lower speeds. This engine is designed to replace the company's current 1.6-liter, 16-valve and will have more power (115hp vs 110) and better torque ranges (90% or more available at 1,500 to 4,000 rpm).
It also includes a stop-start system with ultra-fast startup. When standing still, each piston's position is recorded and when re-starting, fuel is injected into the most favorably-placed cylinder, making restart instantaneous. A regenerative braking system restores power to the battery for use in re-starting the engine.
