1. An engine comprising a trunnion mount for mounting the engine to a chassis, comprising:
a support element connected to the engine having a ring portion with an outer bearing surface, the outer bearing surface of the ring portion arranged concentrically around a crankshaft of the engine, the crankshaft extending through the ring portion,
a female support having an inner bearing surface surrounding the outer bearing surface of the support element, the female support configured for forming a link between the chassis and the engine, and
a rubber bearing arranged between the inner bearing surface of the female support and the outer bearing surface of the support element,
wherein the outer bearing surface of the ring portion and the inner bearing surface of the female support extend in an axial direction and a circumferential direction of the crankshaft coaxially around the crankshaft and are arranged to face each other in a radial direction with a radial distance therebetween, and wherein the rubber bearing is radially positioned between the inner bearing surface of the female support and the outer bearing surface of the support element, and
wherein a rubber surface of the rubber bearing is press-fit with the outer bearing surface of the ring portion and/or the inner bearing surface of the female support such that the rubber bearing is compressed in a radial direction between the outer bearing surface and the inner bearing surface.
