Athena Racing 330 serijos Cooper Ring cilindrų galvos tarpinė.
Šios tarpinės yra su nerūdijančio plieno INOX žiedais, šis technologinis sprendimas gerokai lenkia Fire Ring tarpinių technologiją.
Cooper Ring tarpinės yra taip pat tinkamos pirmam, antram variklio remontui.

Athena privalumai |
|
|
Sustiprinta medžiaga |
OE patvirtinta - tarpinėms gaminti nenaudojamas asbestas |
|
Nerūdijančio plieno žiedai (AISI304) |
Atskiri nerūdijančio plieno žiedai užtikrina maksimalų sandarumą aplink cilindrų angas varikliams, dirbantiems ekstremaliomis sąlygomis, taip pat turintiems NOS sistemą ir/ar turbokompresorių, kai MLS tarpinė nebepajėgi užsandarinti degimo kameros. Cilindrų galvos ir variklio bloko nereikia specialiai apdirbti. |
|
Silikoninis sandarinimas |
Silikoninis sandarinimas yra taikomas svarbiose vietose siekiant pagerinti sandarinimą aplink visas aušinimo ir tepimo angas. |

One of the main advantages of the PMU is continuous current sensing and self-resetting function if the current exceeds a defined level. All output state, voltage and current information can be logged and transmitted via a CAN bus to dash displays to inform drivers of potential problems.
An additional advantage of the PMU system is the ability to define logic for controlling outputs. This is done with data from analog input channels or CAN bus data, and math operations can be defined for each channel. The PMU is also equipped with LED indicators to show the status of each output.
With use of CAN bus keypads or steering wheel switches, all wiring is vastly simplified and lightened.
Two unique features are the inbuilt accelerometer and gyro for logging and “inertia switch” in case of accident.
