Mazda Miata Camshaft

It is the Mazda Miata Camshaft that is the specific conductor that coordinates all the valve movements to ensure that the lightweight roadster breathes, giving the driver instant throttle response and a reputation of being more exceptionally durable than any other vehicle. Made of hardened steel or iron, its lobes drive lifters and rockers to split-second harmony to propel fuel and air into vibrant power without getting out of control with emissions. Lobe spaces and half-crank rotation were carefully spaced in NA, NB, NC and ND generations, which is why one design language can be applied across multiple engines and factory revisioning is straightforward and cost effective because it does not require cross-model speculation. Initial single overhead designs are biased towards plump low-end torque, whereas subsequent dual overhead designs reduce the weight of the valvetrain, allowing redlines to safely exceed 7000 rpm. Introduced in 2004, variable valve timing rotates the intake gear with oil under pressure, providing additional city torque and more top-end power with no adverse effect on the fuel economy, a clever Mazda trade-off in performance and efficiency. A greased Camshaft is also effective in improving efficiency in the reduction of friction, consequently maintaining the coolant temperatures more constant and reducing the load on the pistons when cruising long distances on the highway. It is attached to the crank by a heavy belt or chain to prevent the valves from hitting the pistons, which is extremely important for its safety. Regular oil changes suggested by Mazda sweep away metal particles, and the lobes' mirror surfaces remain smooth beyond 150,000 miles. Compliments are made by drivers on how the sports car continues to pull enthusiastically despite the many years of service, a statement attributed to the robust Mazda metallurgy concealed inside the engine compartment. This well-established balanced valvetrain component fits whether you have a first-year Miata or the recent retractable fastback car, it fits exactly in the same spots to simplify maintenance schedules. The invisible hero is the one that allows a Miata to skip around corners with predictable, easy power as opposed to sporadic bursts. That attitude of mountain roads begins with a Camshaft cut to within two hundredths of an inch of any substance.
