Welcome to the Renault 2.0 idE (F5R) site
In 1999, Renault was the first European gasoline engine with electronic direct fuel injection. It is a modernized unit of Mitsubishi GDI. In order to improve the operating parameters of the engine made a lot of modifications such as changing the fuel pressure and a larger share in the exhaust gas of the fuel depletion. Unfortunately, Renault engineers pioneering work resulted in a silent failure in 2004. This was mainly due to difficulties in meeting the increasingly stringent exhaust standards too high failure rate and power units. However, there was no failure in the engine and engine accessories, focused mainly provided by external suppliers. It was a high-pressure pump, fuel pressure regulator and the EGR valve. When these problems are eliminated, the engine impresses with its performance and fuel economy, and despite the passage of many years, does not stick out its parameters from a much newer design as FSI, JTS, D4, CGI. Currently, in addition to low-cost structure, most gasoline engines are produced in the direct-injection technology, so confident and Renault will have to apologize to the F5R and put back into production engine with direct fuel injection. Unfortunately, most of the above listed failure caused an emergency engine shutdown while driving, leading to a frenzy of owners and completely broke reviews of this engine. In addition, has contributed to the cost of replacing these items as Renault if I qualify for the exchange of the fuel injection system (pump and complete injection rail). As if that were not enough, the service Renault did not provide for the exchange of the regulator but all fuel rail, which required removing the intake manifold and remove the rail with the injectors. Currently, if your Renault IDE warning lights up is not the end of the world, with a little basic knowledge you can remove these items yourself and sent them to rocondition for a fraction of the amount of new items.
Introduction of F5R engine
F5R engine developed by Renault Sport in 2 years at the expense of 15 million as the first Europe's first direct-injection engine with gasoline (IDE).This technology has been successfully used in diesel engines, based on the injection of fuel under high pressure (100 bar) directly into the combustion chamber. The main objective is to improve and increase the efficiency of combustion. This reduces the loss of suction due to low pressure in the intake manifold that the piston has to overcome the piston drawing air into the combustion chamber. The solution adopted to reduce these losses is to increase the pressure in the intake manifold by adding a flue gas. These two strategies allow disclosure of the advantages of direct petrol injection.In the Japanese Mitsubishi GDI engine, depleted mixture is formed by the excess air, this results deviating from the stoichiometric composition of the compound and in particular increases the emission of nitrogen oxides. Therefore Mitsubishi apply additional fuel injection in the vicinity of the spark plug at the time that the ignition mixture was stoichiometric, and was then post-combustion with excess air. The IDE engine, Renault has decided to create lean mixture by adding a large amount of greenhouse gases in which there is no oxygen. Adding an inert gas facilitates the formation of a stoichiometric mixture, and further increases the pressure in the intake manifold by reducing the losses of the engine for improved engine performance.
The engine is based on the F-series engine family F5R IDE is a 16-valve engine with two overhead camshafts developing 103 kW (140bhp) at 5,500 rpm from a capacity of 1,998 cc. The range of Renault engine replaces the 2.0 16V F7R. Although the IDE F5R engine power is slightly less than in the old F7R is noticeably better performance is due to a more favorable torque curve. Reaches a maximum torque of 200 Nm which is a high value for the 2-liter petrol engines and at least 170Nm from 2,000 to 5,650 rpm. The engine is very flexible and snappy acceleration.F5R engine uses less fuel from 15 to 18% less, or 1.5 l/100 km less in the European test cycle MVEG (7.6 compared to 9.1 l/100 km) compared with the previous 2.0 16V engine F7R. To achieve these results, F5R engine uses the same technologies used in the 2.0 16V F4R. They have the same cast-iron block, cylinder, crankshaft, connecting rods, accessories and exhaust manifold. It uses roller bearings and the tappets (valve train friction reduction of 50%), tubular camshafts (reduced weight of 900 grams).Air intake systemThe differences between the two motors are mainly in the head, the combustion chamber and intake manifolds. Motor torque at low speed is optimized by the shape of the intake manifold and resonator which further improves cylinder filling. Kszatł piston crown has been optimized by increasing the mixing of fuel and air in order to get a more balanced load.EGR SystemIn order to achieve pptymalnego combustion engine is equipped F5R (exhaust gas recirculation) EGR, which is mounted below the throttle valve assembly. It is passed under the specified conditions of the exhaust portion of the inlet in order to obtain a mixture containing the fresh air and inert gases. EGR also acts as an additional air inlet, which increases the pressure in the intake manifold, and thus reduces the amount of loss. By optimizing combustion and exhaust EGR adding significantly reduced NOx emissions of nitrogen telnków. EGR is the action when the engine load is from 0 to 50-60%. Outside this range, the EGR valve is turned off.Fuel Injection SystemStrip placed between rollers injection head. There is in pressure from 50 to 100 bar, and directly feeds the injectors. Injection time is controlled by the computer depending on the load and engine speed.
Renault TCe engine
In 2012 Renault introduced again direct injection engine. It is a turbocharged unit 115TCe a 1.2-liter, 115 hp and torque of 190nm at the level of 2500-4000 rev / min. On the basis of this engine was a lot of twin units. This engine is the successor to the engine F4M 1.6 16V 110HP. Compared to him, a number of modifications as direct fuel injection and reduce internal friction by covering sensitive components DLC coating (Diamond Like Carbon), variable capacity oil pump, Start & Stop system. Engine built in the trendy downsizing technology, small capacity and high power and torque. This is to reduce fuel consumption and CO2 emissions. According to Renault, it was a pioneer in the downsizing, introducing early as 1980 F1 V6 engine with a capacity of 1500, and power up to 850HP. The engine has decent parameters on the paper, but mounted in a fairly heavy Scénic and Mégane somewhat disappointing 0-62mph accelerating to 11.7 sec. Engine is more suitable for smaller models like Clio. Also formed units of 0.9 Tce (3 cylinder 90HP) to 2.0 TCe increased unit has a power of 180HP.
