Even tougher 2018 engine grid penalty rules confirmed
http://www.f1fanatic.co.uk/2017/09/21/power-unit-components-will-last-half-season-2018/
From next year the maximum number of engine components each driver may use
without penalty will drop from four to just two for some parts of the power
unit.
Drivers will be limited to two examples each of their MGU-Ks, energy stores
and control electronics. The 2018 F1 calendar features 21 rounds which means
some of these units will have to be used in as many as 11 events.
Of the remaining power unit elements – the internal combustion engines
(ICE), turbochargers and MGU-Hs – drivers will be limited to three examples
of each. These will therefore need to cover up to seven races each.
2018年将使用新的F1引擎使用规则，这将对引擎制造商提出更高的要求。
在全年21场比赛中，MGU-K、ERS和CE使用两套或以下，
ICE、TC和MGU-H使用三套或以下才能免受处罚。
