The D-Type engine is a straight-4 automobile engine from Renault designed to replace the venerable Renault Cléon engine in the Renault Twingo.

History[edit]

The D Engine was designed simply because the "Energy Engine 1.2 Clio by design with its hemispherical cylinder head exhaust up to the front of the head could not fit under the hood early Twingo. The launch of the Twingo 1993 Renault was not thought too the success of this small car, at that time , the Energy engine had recently appeared, it was unthinkable to conceive another engine displacement and power equivalently, the design of an engine generates several years of study and costs are considerable. So to launch its Twingo in 1993, Renault 's legendary spring and proven Cléon-Fonte engine in an exclusive engine ( 1,239 cm3) , which it could fit under the hood of the little Renault , equipping a of single point injection system. The Cleon-Fonte engine is an old design , since it has a lateral camshaft (with rockers and pushrods ) , this engine appeared in 1962 on Renault Floride and Renault 8.

For 1997 , new standards pollution should be applied. Renault could have kept his Cléon-Fonte 1.2 on the Twingo and its Energy engine 1.2 on the Clio , applying changes to its engines, including equipping each multipoint injections, but rather than investing fees studies on two different engines and before the unexpected success of Twingo, it is preferable to opt for a new engine that could both be mounted on the Twingo as the Clio , hence the birth of the "D Engine" . This new engine will be produced D7F1 kind Douvrin by the "Société Française de Mécanique" .

The D engine will be equipped as the Energy engine a hemispherical cylinder head incorporating the camshaft , but exhaust will be placed at the back of the head, in order to get under the hood of the Twingo. On machining cylinder engine has no removable shirts as was the case in Cléon-Fonte engine and Energy engine.

The D7F engine will equip from 1996, the Twingo and Clio 1. It will also be under the hood of the Express Kangoo 1 and Clio 2, Twingo 2 .


D7F[edit]

First produced in July 1996, the D7F displaced nominal 1.2 L (1,149 cc (70 cu in)) and produced 60 PS (44 kW; 59 hp) at 5250 rpm and 93 N·m (69 lb·ft) at 2500 rpm. It had sequential multipoint fuel injection.

Applications:

D7D[edit]

The D7D was a 1.0 8V L (999 cc (61 cu in)) version.

Applications:

D4F[edit]

The D7F was succeeded by the D4F in December 2000. It was the same displacement but added 16-valve heads for 75 PS (55 kW; 74 hp) at 5500 rpm and 105 N·m (77 lb·ft) at 4250 rpm.

Applications:

D4D[edit]

The D4D was a 1.0 16V L (999 cc (61 cu in)) version.

Applications:

D4FT[edit]

In an effort to produce a cost-effective fuel efficient engine Renault introduced a turbocharged version of the D4F, the D4FT, in 2007. Renault named it the 1.2 TCE (Turbo Control Efficiency). This engine features revised 16-valve heads and stronger internals to handle the higher stress caused by turbocharging, resulting in 101 PS (74 kW; 100 hp) at 5500 rpm and 145 N·m (107 lb·ft) at 3000 rpm.

Renault created the break by suggesting downsizing on petrol engines, with the range of TCe engines (Turbo Control efficiency). Tce engine - TCe 100, the best 100 bhp (75 kW; 101 PS) petrol engine due to its driving pleasure and moderate fuel consumption. The TCe petrol engine (Turbo Control efficiency) offers the power output of a 1.4L engine, the torque of a 1.6L engine and the fuel consumption of a 1.2L engine. It is responsive, flexible and has power in reserve while displaying the lowest fuel consumption figures for a 100 bhp (75 kW; 101 PS) petrol engine. It emits only 137 g/Km of CO2 on Clio 3 and 140 g/km of CO2 on Modus and the Twingo GT. These unique qualities are obtained thanks to the combination of a 1.2L capacity engine with a low inertia turbocharger whose response time is reduced to the minimum, through the use of a turbine and a small diameter compressor.It produces 91 to 107 PS (90 to 106 hp) and 78 kW (106 PS; 105 hp).

The turbocharger includes an "overpower" feature which temporarily boosts power output in 2nd, 3rd and 4th gears at engine speeds of more than 4,500rpm (5hp extra power and 6Nm extra torque).

It is fitted to the following vehicles:
