Download in .pdf format Download in .docx format

Proposal to require, in instances where ogive protective covers are fitted to a cylinder, that the covers be removed before conducting the impact damage (drop) test. The proposal further would amend and clarify the need for a gas flow adjuster under UN R110 with regard to the use of carburetors and fuel injectors. A gas flow adjuster is not necessary when an electronic fuel injection system manages the air/fuel mixture and therefore should be removed from paragraph 18.3.1. An adjuster is needed when air/fuel mixture runs via a carburetor and therefore should be added to paragraph 18.3.2.
