WAJA 1.8 - Technical Highlights

Overall
R&H Enhancement on stability & road holding as well as ride comfort with bigger tire size fully enveloped the wheel housing, by giving better proportion also an excellence refine suspension & rubber bushing to absorb the various driving condition without difficulties.

Refine Noise, Vibration and Harshness (NVH) and reduced substantially through various measures at all speed range, typically continental experience.A host of safety features have been incorporated in this model including Air Bag and a better all-disc brake system with standard ABS and Brake Assist to boosts braking power during emergency braking to reduce the braking distance. The ABS brake system is complemented by Electronic Brake Force Distribution, which optimize brake forces between the all the wheel according to the load on board.

An anti-theft safety feature introduces, as standard by applying engine immobilizer system that prevents engine operation via a strategy known as "Software Lock" (or Encrypted Immobilization). The Electronic Control Unit (ECU) of engine is protected using engine immobiliser's key-fork that encoded with 2nd generation rolling code to avoid duplication. This is in-line with the EUROPEAN DIRECTIVE Regulation 95

Powertrain / Engine
A new powerplant generation comes with brand new 4-cylinder DOHC 16-valve engine 1.8-litre. This new engine main attraction is a Variable Valve Timing (VVT) system that enables the inlet valves to have two timing behaviors or patterns. The objectives are to improve the filling of the combustion chambers with fuel/air mixtures and torque output at mid-range engine speed. A mechanism, which increase power and torque, enhances fuel efficiency and reduce exhaust emission levels. VVT, which has already proven technology, enables the engine to perform at its best because the valve timing is continuously altered to suit any driving condition.

When the accelerator pedal is floored beyond 90% travel while engine is revving between 1300rpm and 4250rpm, the inlet camshaft advances the inlet valve timing by 16 degrees. The engine employs a helical spigot and a pressurized hydraulic system to vary the valve timing within 500 milliseconds. This new engine has a higher maximum power of 88kW & 169 Nm torque available between 2000rpm and 4500rpm, and accompanied by reductions of fuel consumption and CO2 emission to pull the body weight at all speed range. The engines include roller cam followers to reduce valve train friction, static ignition with "pencil" coils, hollow camshafts (a weight reduction of 800gms as compared to chilled camshaft) and a compact air filtration system mounted on top of the engine.

Another advance feature in this new engine is Electronic Throttle Body Control a.k.a. Drive-by-Wire. This device adjusts the throttle position, which determines the flow of air and fuel into the engine instantaneously for better response. As a result, reliability and driveability are also improved because the conventional mechanical throttle is no longer used.

Powertrain / Transmission
A new generation Auto-Adaptative transmission (no manual transmission is available at this upon the time) is mated to the new engines, for better response, smoother shifting and better mileage. This auto-adaptative transmission unit aims to provide the feel of a manual gearbox to the more sporty drivers without the need to activate any "sport" or "economy" buttons.

Auto-Adaptative function of driver wishes, road profile and driving condition. The gear control activates downshifting during hard braking into a corner or under prolonged actuation of the brake pedal, shifting lock during quick accelerator release and kick down by software strategy (no switch).

The fuzzy logic is also able to adapt to road gradient styles, thereby contributing to greater fun and fuel economy with safety in mind. This electronically controlled transmission also has overdrive switch, a feature, which helpful for the driver to change the gear position during overtaking or taking hard corner in order to maintain the road grip.
