Alternative fuels are among the most debated topics lately. Much is said in terms of scarcity of resources and future shortage of fossil fuels.
Research is being done in order to find new technologies and alternative ways to feed the engines of our vehicles, focuses on protecting the environment and saving money.
Among various alternatives found, both in Brazil and Argentina there is enough time we use natural gas as automotive fuel; GNV in Brazil, GNC in Argentina or CNG in foreign countries.
Even from the year 2007, brazilian Ford produces a version of the Ranger already factory equipped with natural gas fuel system. Is nothing more than a hybrid vehicle that works using tetra-fuel: natural gas, gasoline, ethanol and the mixture in any proportion of ethanol and gasoline.
The Duratec engine is the 2.3, a four-cylinder 2.3-liter, four valves per cylinder and power of 150 hp at 5,250 rpm. It's the same engine used in Fusion, with some changes to prioritize the torque, which in the truck is 22.3 lb.-ft. at 3750 rpm. To receive the changes were made in the CNG cylinder head with valve seat enhancements and improvements of their own intake valves.
The fifth-generation kit is the most modern available and eliminates all the drawbacks of this system. Using CNG, according to Ford, there is a loss of about 11% in power (depending on the quality of the installation). Are 133 bhp and 19.5 lb.-ft. of torque, always in the same range of rotation. Ford aims to increase the autonomy of 225 km of Ranger with the use of CNG. The factory also claims that the risk of flash-back ("back-fire"), with ignition of accumulated gas in the intake manifold, was eliminated.
The fuel switch is done through the button panel, easy access to the driver. The change is noticeable when the vehicle is stopped or running at low load the throttle - except for a slightly higher roughness of the engine when running on CNG. If the exchange is performed in time to accelerate further, there is a slight jolt. You can easily maintain cruising speed of around 110 km / h, except in incorporated by slower, is not perceived to be using gas.
The start is always performed with gasoline, so Ford recommends that let the fuel tank fueled at least in one quarter of its maximum capacity (60 l in the single cabin, double cabin in 75 l).
The pickup had increased in weight over 100 kg, plus cylinder (empty) and all components of the kit. Besides the smaller space in the bucket, the gadgets that interferes with the performance of the vehicle, as evidenced in the evaluation. You should also consider the increased wear of the brake system and suspension, which will run forever with that much weight.
I've used it for two years in my Ranger 4.0... a fourth-generation kit with aspirated system GNV and not have to complain about; the system is safe and effective and I'm very happy with my Ranger.
