Renault Sport F1 boss Cyril Abiteboul believes limited use of standard parts in F1's future engine regulations could help alleviate fears of cheating in the sport.
Ferrari recently came under the scrutiny of the FIA after its rivals had expressed their suspicions about the SF70-H's hybrid system.
The Scuderia's car was deemed as legal by the governing body, but the ever-increasing complexity of F1's power units has generated fears that engineers could seek equally complex ways of circumventing the rules.
For Abiteboul, introducing elements of standardization in the future could reduce those fears among competitors.
"I don't want to create a debate here, but I think we need to think how we can help the FIA, regarding the enforceability of the regulations," Abiteboul told Autosport.
"I really believe that the complexity of the engine is such that I would not want to have myself to police it. So I think we need to figure that out.
"I really believe that some elements of standardisation are not just useful but absolutely necessary if we want to retain some confidence between all the participants."
Abiteboul admitted that currently, opportunities exist for Renault's engineers to beat the rules, with the team refraining from going down that dodgy path for obvious reasons.
"I think that, frankly, if we wanted to cheat on the current engine, we would know how to do it, and that's an issue," said the Frenchman.
"We are a very large corporation and we would never do such a thing like that, we can't afford the reputation risk.
"I'm not saying that anyone is cheating, but I think it'd be good to get rid of all the speculation, by doing some local and targeted standardisation, and we've put forward some proposals in relation to that."
