Advanced Digital Engine Management, Fuel Injection and Emissions Control Suzuki Suzuki GSXR 711 2011

Each cylinder's secondary injector is mounted at a 15-degree angle and is aimed to bounce sprayed fuel off the The primary injector for each cylinder has been repositioned at a shallower, 35-degree angle from the throttle-body centerline, spraying atomized fuel below the primary butterfly valve and directly down the intake port, improving throttle response. The primary injector for each cylinder operates under all conditions, and the secondary injector adds more fuel during high-rpm, high-load operation. The latest fine-spray injectors each have 8 small holes for improved fuel atomization, which contributes to more complete combustion.

The result is more linear throttle response, increased torque and reduced emissions. The secondary valve is controlled by the ECM, which monitors engine rpm, primary butterfly valve position (or how much throttle the rider has selected) and gear position, then opens or closes the secondary butterfly valve incrementally to maintain the ideal intake air velocity for improved cylinder charging and more efficient and complete combustion. The primary butterfly valve in each throttle body is linked directly by cable (which provides a positive, instantaneous connection between the rider and the machine) to the throttle grip operated by the rider. At the heart of the SDTV system are two linked, double-barrel downdraft throttle bodies, each cylinder getting its own tapered barrel carrying two butterfly valves and two compact fuel injectors. The ECM operates a state-of-the-art Suzuki Dual Throttle Valve (SDTV) closed-loop fuel injection system, an advanced ignition system and several emission control systems, producing better throttle response, smoother power delivery, improved mileage and reduced emissions.

 The GSX-R features a repositioned engine management computer (also known as the Engine Control Module, or ECM) to allow the wiring harness to be simplified and made lighter.

Efficiency By Design Suzuki Suzuki GSXR 711 2011

The shorter wheelbase better centers the combined machine/rider mass between the wheels, Rotating the engine rearward by 3 degrees around the countershaft sprocket made it possible for the engineers to reduce the distance from the front axle to the swingarm pivot while maintaining the race-proven steering geometry and without losing the needed clearance between the front wheel and the radiator at full wheel travel. The GSX-R750's wheelbase is now 1390 mm. A Lighter, More Compact Chassis The new GSXR750 features a completely new chassis designs, based on a more compact, lighter twin-spar aluminum frame with a 15 mm shorter wheelbase. Suzuki engineers paid special attention to making both the new GSX-R750.

In turn, a better power-to-weight ratio can produce stronger acceleration, better fuel mileage and reduced emissions in many situations. The more power and torque the engine makes and the less the motorcycle weighs, the better the power-to-weight ratio becomes. Performance efficiency is best expressed by the power-to-weight ratio, or, the comparison of a motorcycle's output to a motorcycle's weight. Reducing mechanical losses by minimizing internal engine friction, reducing the weight of reciprocating internal parts and relieving crankcase pressure can increase mechanical efficiency, putting more of an engine's output to use actually moving and accelerating the motorcycle and also improving fuel mileage and reducing emissions.

Mechanical efficiency is a measure of how much of the power and torque produced by an engine actually reaches the rear wheel. Better combustion efficiency can increase power and torque output across the rpm range; improve throttle response, acceleration and fuel mileage; and reduce emissions. Combustion efficiency, for example, is a measure of how completely an engine burns its fuel.  Efficiency By Design Efficiency is an important motorcycle engineering consideration.

The newest GSX-R750 is a full 8 kilograms lighter, with a curb mass of 190 kilograms. The new machine is built on a more compact, 15mm-shorter wheelbase with race developed chassis geometry, suspension and brakes, with simplified and lighter aerodynamic bodywork. The 2011 GSXR 750 features advanced engine technology, with broader power delivery, improved throttle response, lower emissions and about 10-pecent better fuel mileage as measured by Suzuki engineers using the standardized Worldwide Motorcycle Test Cycle. Would-be competitors finally gave up racing against the GSX-R750, and then stopped building 750 Supersports altogether.

In the decades since then, the GSX-R750 has consistently outperformed anything else in its class, proving the slogan, Own The Racetrack. Take what is learned in professional racing, and apply it to production models in a continuous loop of engineering improvement. Concentrate on overall performance, not simple fashion. The original GSX-R set a design theme Suzuki engineers have followed with success ever since: Make the GSX-R respond to the rider and do what the rider wants, when the rider wants, how the rider wants. And the newest version of the bike, the 2011 GSX-R750, will continue to shock.

When the Suzuki GSX-R 750 was introduced in 1985, it was a total shock to the motorcycle industry.
