| Document title | UN R110: Proposal for a Supplement to the 02 and 03 series of amendments | ||||||||||
| Date | 20 Jul 2018 | Proposal to 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. | |||||||||
