Is the engine loaded on the current Suzuki Altworks amazing?｜ Dr. SUZUKI Works History Course _Vol.9

Inside the engine room of the current Suzuki Altworks.The air cleaner and the intercooler are equipped with a dedicated inlet duct, making it a structure that actively incorporates the outside air.

The current Alto Twin Cam Turbo Works.The installation of the DOHC4 valve 3 -cylinder turbo engine is a tradition that has been from the first generation.The fifth generation is dedicated by adding tuning to the existing improved R06A.The transmission was also given a dedicated tune, and Suzuki's proud engine characteristics were brilliantly linked.Popular serialization, Weekly [Speaking of Suzuki Alto Works].When you start talking about Works (?!), Dr. Suzuki's "Works History" is a serialization.Text / Photo: Dr. Suzuki (Dr).Suzuki) Photo: Rev Speed / Swift Magazine with Alto Works

The improved R06A engine is mounted on many Suzuki vehicles

The improved R06A also has an air cleaner case and an intercooler on the engine.Pursued small, lightweight, and mountability.By the way, unlike the K6A type in the block, there is a crank cap.

The center is the exhaust port of the exhaust manifold, and the exhaust of the three cylinders is gathered.The exhaust entrance of the turbo comes here.The route to the turbine is the shortest, the energy of the exhaust can be used efficiently, and the turbo operates from low speed

The engine mounted on the current Altworks is made of all aluminum following the K6A type.The improved R06A engine is a kind of general -purpose unit that appears in many Suzuki vehicles, but the mechanism is a DOHC4 valve three -cylinder turbo.Bore 64.0mm x stroke 68.The ratio of 4mm is the longest stroke among the engines in successive works.The compression ratio is also 9.1 and Works' DOHC head is the highest.In the head, the valve is a cam direct hitting type.The shape of the port, the angle of the flow path, the shape and cooling of the combustion chamber are boiled down.The exhaust manifold is also integrated with the head.These mechanisms are evolving from the base R06A, and is because of the improved name.The mounting turbo is an IHI RHF3 type, and the air volume is similar to the fourth generation, but the latest is excellent.The A/R on the turbine side is 6, which can be said to be a specification that matches the characteristics of the engine itself.

ECU and cooling system are exclusive.The torque band is a common area

Inside the engine room of the current Suzuki Altworks.The air cleaner and the intercooler are equipped with a dedicated inlet duct, making it a structure that actively incorporates the outside air.

New and high efficiency.The displacement is large.Stroke is long.Control dense.The lower the conditions, the thicker the low and medium -speed torque.Therefore, the improved R06A has a very good practical range from low rotation to 6000 rpm.

The features of the improved R06A are VVT -intake side variable valve timing mechanism and electronic throttle.Yes, it is a function in the early days of the fourth generation.For 36 Works only, the cooling system is first.Due to stabilizing the combustion temperature, the opening temperature of the thermostat was lowered from 88 degrees to 82 degrees of the turbo RS.Next is the introduction of the outside air into the engine room.In fact, the Works emblem of the front grill is slit.From there, we try to incorporate a driving wind and apply it to the heat.And the ECU of the dedicated program that makes use of the above.The accelerator response is more sensitive and faster than the turbo RS.The boost is about 0 at low rotation due to the supercharging control control.It costs 9kg/cm2.The maximum output is 64ps/6000rpm for 7200RPM Leb, maximum torque with only 3000 rpm.It reaches 2kgm.The torque value is 0 of the anti -turbo RS.With 2kgm up, we are proud of the top torque weight ratio in the current sporty model.This is the source of Works acceleration.
