ignition coil introduce

With the development of gasoline engines in automobiles towards high speed, high compression ratio, high power, low fuel consumption, and low emissions, traditional ignition devices are no longer suitable for use. The core components of ignition devices are ignition coils and switch devices. By increasing the energy of the ignition coils, the spark plug can generate sufficient energy to produce sparks, This is the basic condition for the ignition device to adapt to the operation of modern engines. The ignition coil is divided into two types according to the magnetic circuit: open magnetic and closed magnetic. The traditional ignition coil is used with an open magnetic type, and its iron core is stacked with about 0.3 millimeters of silicon steel, with secondary and primary coils wound around the iron core. The closed magnetic type uses an iron core similar to III to wrap around the primary coil, and then wraps around the secondary coil outside. The magnetic field line is composed of an iron core to form a closed magnetic circuit. The advantage of the closed magnetic ignition coil is that it has less magnetic leakage, Due to its small energy loss and volume, electronic ignition systems generally use closed field ignition coils)

Porsche Macan introduce

The Porsche Macan is a mid size SUV The term "Macan" originates from the Indonesian translation of "tiger". As a mid size SUV of Porsche, the Macan adopts the chassis of the Audi Q5, equipped with Michelin tires [1]. Porsche's family style front face is not lacking, and its unique hatchback design is fundamentally different from the Q5. In terms of design, it tends to be more sporty, making it look like a crossover car The launch of Macan fills the gap of the Porsche brand in the mid size SUV market, sparking a new round of competition in the market with high brand value, sporty styling, and differentiated customization services The entry-level Macan model is equipped with a 2.0-liter inline four cylinder turbocharged engine, with a maximum power of 173Kw; The mid-range configuration is equipped with a 3.0L V6 twin turbocharged engine, with a maximum power of 250Kw; The flagship model is equipped with a 3.6L V6 twin turbocharged engine with a maximum power of 294kw. On November 10, 2018, the all-new Porsche Macan was officially launched
