Abstract
Cold start performances in an engine of a wax-containing fuel may be assessed by drawing said fuel from a container under standardized conditions through a filter and measuring the rate of flow of fuel past said filter and comparing said flow rate with a flow rate obtained under the same conditions with a fuel of known cold start performance. This provides a relatively quick and simple indication of whether an engine running on such a fuel at the test temperature might be expected to have its filter blocked by the wax, preventing it from starting.
