Fuel Submission Guide: Scope, Format & Tips (2026)

Fuel follows Elsevier's standard formatting with specific requirements for fuel science papers.

• Manuscript structure:
• Title page with complete author affiliations
• Abstract (250 words maximum, structured with Background, Methods, Results, Conclusions)
• Keywords (6-10 terms from Fuel's keyword list)
• Introduction
• Materials and methods (or Experimental section)
• Results and discussion (can be combined or separate)
• Conclusions
• Acknowledgments
• References
• Figure captions
• Tables

• Figure requirements: Submit figures as separate files in TIFF, EPS, or PDF format. Minimum 300 DPI resolution for photographs, 600 DPI for line drawings. Color figures are encouraged for combustion and emission data visualization.

Size figures for single-column (85mm width) or double-column (170mm width) placement. Don't submit oversized figures that require excessive reduction.

Label all axes clearly with units. Use consistent font sizes (minimum 8-point after reduction). Include error bars on experimental data points.

• Reference style: Fuel uses numbered references in order of appearance. Format: Author(s), Article title, Journal abbreviation, Volume (Year) Page range.

Example: Smith AB, Jones CD. Biofuel combustion characteristics in diesel engines. Fuel 285 (2021) 119-127.

Include DOI when available. For books: Author(s), Title, Publisher, Location, Year, pp. page range.

• Elsevier-specific requirements: Submit through Editorial Manager with separate files for manuscript text, figures, tables, and supplementary material. Upload a cover letter addressing the editor directly.

Include a graphical abstract (required) showing your key finding visually. This gets used in journal promotion and should highlight your main combustion or fuel result.

Provide author contribution statements and conflict of interest declarations. These are mandatory for all submissions.

Your Fuel cover letter should directly address why your fuel science advances the field and how your combustion data supports practical applications.

• Opening paragraph: State your manuscript title and article type. Briefly summarize your fuel system and key combustion finding. Mention if your work addresses a current fuel challenge like emissions reduction or renewable energy integration.

• Technical contribution: Highlight your novel fuel characterization or combustion technology. Be specific: "This work demonstrates that 20% algae biodiesel blends reduce NOx emissions by 15% while maintaining power output in heavy-duty engines" rather than "This work studies biodiesel performance."

Mention your analytical approach and why it's appropriate for fuel science. If you used advanced techniques like chemical kinetic modeling or detailed speciation analysis, explain how this advances understanding.

• Practical significance: Connect your results to real fuel applications. Explain how your findings could influence fuel formulation, engine design, or emission control strategies. Fuel editors prioritize research with clear practical implications.

• Suggested reviewers: Recommend 3-4 reviewers with specific expertise in your fuel type and combustion application. Include their full names, affiliations, and email addresses. Avoid close collaborators or colleagues from your institution.

Close professionally: "We believe this manuscript makes an important contribution to fuel science and would be of broad interest to Fuel readers."

Fuel's review process takes longer than most journals due to the technical depth required for combustion research evaluation.

• Initial screening: 7-10 days. Editorial staff check formatting, scope alignment, and basic technical completeness. About 15% of submissions get desk-rejected here for insufficient combustion data or poor fuel characterization.

• Editorial evaluation: 14-21 days. The handling editor (usually a combustion professor) evaluates technical merit and novelty. Another 10% get rejected without review if the contribution isn't sufficient for Fuel's standards.

• Reviewer assignment: 21-35 days. Finding qualified reviewers for specialized fuel research takes time. Fuel typically uses 3 reviewers with different expertise areas.

• Review completion: 100-130 days total from submission to first decision. This includes reviewer delays, which are common in specialized combustion research.

• Revision timeline: Major revision decisions give you 60 days to respond. Use this time for additional experiments if reviewers request more combustion data or fuel analysis.

Minor revisions typically get 21 days. These usually involve manuscript clarification or additional discussion of results.

Resubmitted manuscripts get expedited review (30-45 days) with the same reviewers when possible.

Don't rush revisions. Check if your paper is actually ready to submit before starting the revision process.

In our pre-submission review work with manuscripts targeting Fuel, five patterns generate the most consistent desk rejections worth knowing before submission.

According to Fuel submission guidelines, each pattern below represents a documented desk-rejection trigger; per SciRev data and Clarivate JCR 2024 benchmarks, addressing these before submission meaningfully reduces early-rejection risk.

• Fuel characterization without combustion performance data (roughly 35%). The Fuel guide for authors positions the journal as publishing research on fuel properties, combustion, and energy conversion with both fuel characterization and performance data required. In our experience, roughly 35% of desk rejections involve manuscripts that report density, viscosity, heating value, or chemical composition without demonstrating how those properties translate to combustion performance under realistic conditions. Editors specifically screen for manuscripts where the connection between fuel properties and combustion outcome is present in the results, not asserted in the abstract.

• Lab combustion data without engine or device validation (roughly 25%). In our experience, we find that roughly 25% of submissions test combustion in idealized laboratory setups, such as atmospheric-pressure bomb calorimeters or simplified combustion chambers, without validating performance under realistic engine or conversion conditions. In practice, editors consistently reject manuscripts where the combustion testing does not reflect the operating pressures, temperatures, and fuel-air ratios that characterize actual engine performance, because Fuel's editorial standard requires evidence of combustion behavior in systems that correspond to real applications.

• Emission reduction claims without rigorous measurement validation (roughly 20%). In our experience, roughly 20% of submissions report NOx, particulate, or CO emission results without validated measurement equipment, appropriate sampling procedures, or quantified measurement uncertainty. Editors consistently screen for manuscripts where the emission methodology is documented in enough detail that the claimed reduction can be evaluated independently, because claims about emission performance that rest on unvalidated measurement approaches are a consistent source of reviewer objection.

• Functional interpretation exceeds what the combustion data support (roughly 15%). In our experience, roughly 15% of submissions frame their contribution in language that overstates what the experimental data demonstrate, such as claiming practical deployment readiness from a single-point combustion test or attributing emission improvement to a proposed mechanism without kinetic or spectroscopic evidence. In our analysis of submission difficulties at Fuel, this pattern is most common in submissions where the discussion section reached beyond the experimental evidence without acknowledging the interpretive gap.

• Cover letter names fuel type but omits the combustion outcome (roughly 10%). In our experience, roughly 10% of submissions arrive with cover letters that identify the fuel system or feedstock studied without stating what the paper demonstrates about combustion behavior, emission performance, or energy conversion efficiency. Editors explicitly consider whether the cover letter makes the technical fuel-science case before routing the paper for specialist review.

Before submitting to Fuel, a Fuel submission readiness check identifies whether your combustion evidence, fuel characterization, and practical application framing meet the editorial bar before you commit to the submission.
