Trionic T5.2

<h2 id="features">Features</h2>
<p>Its <a href="/facts/Engine_Control_Unit/Q1uYhmyN">Engine Control Unit</a> is based on a <a href="/facts/Motorola/ztqczx68">Motorola</a> 32 bit <a href="/facts/CPU/Jxp1bqMV">CPU</a>.
</p><p>The Trionic T5.2 uses a <a href="/facts/Mecel/Xc9yTa9Q">Mecel</a> patented ion-current measurement1 to decide which cylinder was in the compression phase and had just ignited the air/fuel mixture. The ion-current measurement is thus used to synchronise the ignition's firing of the spark plug with the cylinder which is full of compressed air/fuel. This ion-current measurement can also determine whether there had been detonation or knocking when the cylinder fired. Finally, the ion-current measurement can be used to identify a misfire with outstanding accuracy. 
</p><p>Trionic T5.2 uses a MAP (Manifold Absolute Pressure) sensor to, indirectly, measure the weight of the air that has been drawn/forced into the cylinders. It uses a simple slotted aperture disc in conjunction with a crank position sensor to identify the Top Dead Center (TDC) for cylinders 1 & 4 and also to measure the engine's RPM.
